menu Bar and dock problems - MenuBar won't highlight and Dock freezes

Move the com.apple.dock.plist and com.apple.dock.db files to the Desktop, log out and back in, reset the Dock preferences using the prefPane. If that fixes your issues, delete the moved files and repopulate your Dock with the desired apps and folders. For the menu bar issue, move the com.apple.systemuiserver.plist file and repeat the steps.

Can't help as i don't have multiple monitors or laptops.

Thanks for the feedback. Good computing.

SS2 - i have the same problem. im running OS X 10.6.5 on a mac Mini with an external LCD display. My dock does not respond to presence of the cursor - i.e., won't come out of hiding, no magnification and the cursor is no longer capable of highlighting options in the drop down menus when you 'hover' over them. everything works on hard-clicks. sounds similar to your issues. it was working perfectly until 30 minutes ago and all of sudden this problem just popped up out of nowhere. i too have a logitech cordless mouse, but i didnt have these problems 30 minutes ago...and i have had the same mouse.
how did you solve it? thanks in advance

I'm having a similar, although identical problem using a Macbook Pro running 10.6.4. I have the Dock hidden and suddenly over the last couple of days it has started freezing, Finder stops responding and won't relaunch, and cmd-tab won't show running apps (I assuming cmd-tab is part of Finder?).

Chrome in particular also seems to be freezing up. The only big update I can think of recently is the new iTunes, but otherwise I can't think of anything significant. I'm also having problems on my iMac, which suggests it may be to do with some recent system/software update. Hopefully somebody finds a resolution. I'll post anything further if I have any success.

Things are definitely still not right.

The most disturbing thing is Finder not responding ("The application Finder.app can't be opened." with code -10810), and not relaunching when killed from either Force Quite or the Activity Monitor. Also Aperture would simply fail to start (just startup then freeze with 'not responding') and after a couple of freezes it did start up ok.

I did a bunch of 'housekeeping' uninstalls including Adium, which I'd recently installed, and Chrome (as well as a bunch of random apps that I don't use) and it seemed to have only improved stability - it's still screwing up pretty randomly.

I reinstalled Chrome and still seems to be ok (Aperture still starting ok), although I can't really say I trust it as Aperture did fail a couple of times before it started ok (I didn't keep a strict log of exactly what sequence of uninstalls/reinstalls/reboots I carried out), and also iTunes froze as well, although that too has now started ok - I don't use it regularly so I haven't started it since then.

Basically now that everything's running I haven't done much else to experiment.

Doh! Stupidly I've just started iTunes again "just to see" and it's frozen, along with Finder. (*£&$ing ****!!!!!! (This is on the iMac - everything else is still running, and if you're reading this then I was still able to post it from Chrome.)

Something is definitely wrong with my system(s). I guess I'll leave it a week or so and see if an update comes out before I take the Macbook Pro to a Genius bar somewhere for a rant.

I have the same problem and tried everything you said from trashing plist file to reinstalling snow leopard but the problem seems to recur again and again..any new solution guys or should go ahead with a fresh install?

I have had this annoying problem for about a week now.
I've tried every solution, from zapping the P-RAM, to completely reinstalling Snow Leopard, and re-updating to 10.6.4. I've tried to resolve permissions, repair disk, unplug everything, etc. etc. and nothing helps. I thought "Maybe it's my tablet software!" I tried un-installed , tried a regular mac mouse, and instigating it again and the problem still arose. This has occurred in any application possible.

+How it happens:+ When I type, or even select sometimes, a value box. For instance [ %100 ] I select the box, change it to [ %200 ]. It doesn't seem to affect Text Boxes (like this one). it affects Web Browsers and FTP managers, Digital design apps, or Games.

+The result:+ The desktop freezes; or does it? The keyboard works. The cursor works. However, the desktop doesn't react to the cursor. I can change windows, using the keyboard, and the dock WILL notice the cursors presence, if I repeatedly switch the audio/brightness mods. This doesn't change the fact I can't click. I've tried waiting -- HOURS -- for it to stop, and it's not a temporary problem. I have no Logitech software, or mice around.

Conclusion: It's a HUGE waste of time, having to hard restart every time this happens.

I'd like to find some sort of Help for this problem; This... error.

I reinstalled OS 10.6 on my 27" iMac and developed this problem:

• the curser is a text cursor when it should be the default or a hand
• menu items don't highlight on mouse over
• the dock won't respond to mouse over
• finder will close down on relaunch but doesn't always restart

So far the only solution I've found is to restart the machine–after about 10 minutes the issues resume.

After trying everything I could think of (resetting PRAM, deleting caches, plists, etc.), I reinstalled again, opening no applications and careful not to touch anything until all new updates were installed.

And with that, it's back to normal....
