How do I get mouse zoom to work in Lion?

I havezoom off in universal access and my magic mouse zoom holding ctrl and moving one finger up and down.

Restart computer and try.

I had the same problem. Then I started messing around with the zoom system preferences and it all got screwy. The screen expanded out so far I couldn't get to any of the control icons, couldn't shrink the screen. Finally had to restart by pushing the power/start key on my Mac Air. When it booted up it came back to the expanded screen but the control/scroll worked this time so I could get it back to normal. There's obviously a bug with this as I've seen other posts here and there about similar issues. If you can leave feedback with Apple so that hopefully this will be addressed with the other issues as well.

I have the same problem. It was working fine.. New mac mini went to sleep.. Woke up in the morning and it stopped ctrl zooming. This appears to be an issue with Lion. I am 100% certain that restarting the computer will fix the problem, but users shouldn't 'have' to do that.

Please elevate to have the next release include a bug fix.

I have the same problem with my early 2008 MacBook Pro!

And I've got the same problem on my iMac i& (late 2009). Called support and they acted like this is unreported. Just emailed accessibility@apple.com...

I've noticed other mouse and keyboard weirdness. So it may not be limited to Zoom.

And gosh apple, bring back color sidebar icons. Sorry, off topic:)

I have the same problem with my 2009 Mini and my 2008 MacBook Pro. Restarting seems to work, but then it stops working after a while, for no apparent reason. May be linked to sleep or screen saver, I am stil experimenting. Frustrating, keep pushing to apple and maybe we will get a fix.

I have the same problem on my late 2007 15" Santa Rosa MBP. Durn it, i liked that feature.

I found that if I cycle the screen saver (with the hot corner), the full screen zoom works again. No need to restart! Yay

After reading and trying all the suggestions in this thread I found that all were tempoary, the bug keeps coming back and the only solution (so far) is to restart the computer. This is unacceptable so I searched for a third party solution.

There is a utility called Point N See that is Lion compatible. It provides a simple zoom in a window. It's not as elegant as the native zoom but it works. Find it at http://customsolutionsofmaryland.50megs.com/pointnsee.htm/.

I found this in other discussion and it works for me:

I concur. It stops working if the display goes to sleep while the Screen Saver is active. I found that the zooming can be restored without a reboot or logout if you force the Screen Saver to activate via one of the Hot Corners. This is clearly a bug.

Thanks for this tip. It does indeed work. I've been sharing my findings with accessibility@apple.com. Hope we see a fix in the next OS update. This tip is a big help.

I have window zoom set for ⌥ Scroll. It often doesn't work, but suddenly it just starts working without a restart.

Universal Access zoom works completely differently.

This morning it works from the get go.

PS. I also use a trackpud; zoom works with both magic mouse OR NOT BOTH, so it must be software not hardware problem.

Oh, I'm sure it's software. I have a mouse, and a magic trackpad. Both work the same, either both work, or both don't work:)
