After updating to Lion my mouse pointer will sometimes disappear on my second monitor. If I move it back to my primary monitor is will return. Doesn't happen with any regular occurrence, seems pretty random. Thoughts?

******************** I HAVE SOLVED THIS PROBLEM (at least for me) ********************
Ok so I literally just "fixed" it accidentally while working on another tip from another thread.
Going into System Preferences --> Accessibility --> Display, I increased the "Cursor size" and tada! Now it shows up on all screens.
Interestingly/bizarrely, playing around with this feature, it only worked once the Cursor size got about 2/3 between "Normal" and the first tick to the right. Any smaller and it disappears again. This seems strangely arbitrary and I can't figure out why this works. I would think maybe it has something to do with relative resolutions of the monitors but that wouldn't explain why it displays fine on the second, mirrored, monitor.
Hope this helps someone else!
No need to reboot, just hover your (invisible) mouse over the Dock and it will reappear. I'm so used to this bug in Mountain Lion 10.8 that I will almost miss it when they fix it (which I suppose they will in another year or two).
When I hover over the Dock, the cursor does reappear, but only briefly. I sometimes didn't make it back to the top of the screen before it disappeared again -- and I'm working on a laptop!
The reboot seems to have worked -- at least for the last several hours. I'm hoping to never see (or not see) that particular bug again!
Just fixed this problem so I thought I'd share the solution with anyone still having it: I had a suspicion it had to do with desktop icons that appear at the edge between both screens. I put all my desktop files into a separate folder so the only thing that remained on the desktop was the Macintosh HD icon. I rebooted and the cursor now appears on both screens.
Hope that helps.
I've been having this issue with my 2015 imac (thunderbolt/display port) and now my new 2017 imac (USB C), across multiple OSX updates.
I have three monitors:
1) My primary imac display
2) A secondary 1080p dell monitor
3) My 1080p TV
Monitors 2 and 3 are mirrored. My mouse cursor doesn't show on one of them but DOES show on the other. If I switch which thunderbolt/usb-c port they're plugged into, the problem switches displays.
Can't figure out what could be causing this. Just seems like a bug in apple's display software. It's amazing to me it's not fixed yet, as it's been three years.
I've just started having this problem too. It seems to correct itself after a short while but is quite frustrating all the same. Maybe a reboo will fix it... (haven't done that myself yet though)
I've been having this issue as well. The mouse reappears after an app changes focus. Hopefully it gets fixed in the next update.
Not fixed in yesterday's update 10.7.1,
I have encountered the same phenomenon. And other glitches if you are working with Xcode.
Same problem here on 2008 white macbook with two different monitors.
I have same problem. Losing it when going from the secondary to primary monitor. Its either Lion or the magic Trackpad or the combination of the two. I am also using XCode.
Yes, I have 10.7.1 and it still goes away however I've found that a click once the invisible cursor is on the other monitor makes it come back.

I'm also having this issue. Sometimes the cursor disappears on the 2nd monitor. After changing the focus of some applications / playing around it quickly reappears.
I just installed the latest Thunderbolt update from Apple today. I think this update fixed the cusor disappearing issue.
No fix in today's update, 10.7.2.
Hi Negatetime,
Are you using any other pointing device like Wacom tablet? Because I found that my problem is caused by Wacom, if I use mouse, the mouse cursor will not disapear on my second monitor.
Mouse pointer disappears on second monitor.
