Is screen zoom broken in Lion?

For years I've zoomed the whole Mac OS X screen with Control ⌃ + two finger scroll on the trackpad.

It was very useful when giving demos and when wanting to zoom in on a YouTube video.

Since I installed Lion it was working, then it stopped working, then worked again, now it's not working.

What am I doing wrong, or is it just broken?

Solution 1:

I had this problem with Leopard and it continues in Lion. The only solution that works for me is to reboot. Changing the settings in system preferences does not work on my machine.

Solution 2:

You now have to manually enable it.

1. Go to Universal Access in System Preferences
2. Turn on Zoom with the radio button.
3. Click on Options and tick Use scroll wheel with modifier keys to zoom.

Solution 3:

I experienced a similar problem in the Developer Previews of Lion. A restart always fixed it.

I've not had any problems since I installed the GM public release build.

If you are experiencing such problems I suggest sharing feedback, and filing a bug report.
