Glitch after using keyboard shortcuts

Hello,
I seem to continually having a glitch after using the keyboard shortcuts for zooming (+ & -) on my Mac OSX 10.6. I’m using Blender 2.58.

The glitch stops me from zooming, Tabbing out of edit mode, selecting and moving vertices. The only way to fix it is to switch to another program and back again. I think it’s the keyboard locking up??

Anyone else have this problem?

Thanks,
Tim

Never seen that issue, but you might try upgrading from 2.58 to 2.59(stable). Might have been a bug that’s already been fixed.
