10.6.3 Mouse keeps freezing and keyboard problems

So, I installed 10.6.3 using software update and was experiencing mouse freezing problems along with keyboard glitches (letters not typing, freezing). It seemed like it was mostly happening in Safari, but then I tried Chrome and the same problem.

Decided to reinstall using the combo update... same problem.

Anybody else having this problem. It's pretty intermittent. I managed to get through this post with no problems, and the mouse is still working.

The only way I get the mouse to move again is to shut the laptop, let it go to sleep, and then upon opening it up again, the mouse is functional. But, it's definitely happening only since 10.6.3.

Macbook Pro, Mac OS X (10.6.3)

I, too, am having problems with intermittent mouse freezes upon installation of 10.6.3. The system still accepts keyboard input (albeit slowly) when the mouse is frozen. The mouse unfreezes after a while (on the order of 30 seconds). The freezing/unfreezing behavior seems to be uncorrelated with my actions. To date, I have had freezing while using Igor Pro, MS Word and Safari, so the problem is not confined to one application.

This is definitely a result of the 10.6.3 install.

I am also having similar problems. The Apple USB Keyboard isn't recognized but the Logitech wireless mouse is. Then if I try to open a finder window I get an error message:
The application Finder.app can't be opened.

I have rebooted several times since I updated to 10.6.3 this morning with the same result each time. I had never seen the error before the update.
The Mac Pro is basically unusable without a keyboard or Finder so I hope there is a fix soon... Help!

Immediately following the reboot after installing 10.6.3, the keyboard & trackpad no longer function on my 2-week old MBA. The USB mouse is fine. After a cold reboot, the keyboard SOMETIMES functions for about 1-2 minutes, then goes dead with no response whatsoever from any key or the trackpad and it stays that way, never regain keyboard functionality again until the machine is turned off/on. Usually, though, it's just DOA. The login screen, though, always allows keyboard input; it's not until after the desktop draws that the keyboard dies.

Since it's a brand new box and only 2-weeks old, I haven't installed ANY software whatsoever. Whatever software Apple preinstalled is all that is on this machine so it's not a conflict with anything I've installed.

Rebuilt back to 10.6 and everything is OK again.
