Need advice. Upgraded to yosemite on my mid 2011 iMac.I'm having tons of problems: mainly Photoshop CS6 keyboard shortcuts for brushes, zoom even Save undo etc stopped working as well as severe lag in processing using brush tool. I use a Wacom intuos 3 tablet which i have installed latest driver. I have now installed the white box plug-in that has helped the Brush keyboard command, but now all kinds of new errors are occurring: in utilizing the eyedropper too, l the color picker. i get a window saying: "could not complete your request because of a program error" (!!!) this has rendered my Photoshop CS6 completely unusable [and i'm on deadline!]. Any advice would be greatly appreciated! coul it be Font explorer pro which has been closed during all these scenarios. could it be the 3rd party custom brushes i purchased that are highly regarded and super crucial to my artwork? Is there any way to pin point the problem without uninstalling things? I'm just stuck. Please help!

Do you have any third party plugins loaded? Have you tried disabling them?

Does it only give an error after using the crop tool?

Yes, the Font Explorer Pro plugin may need to be updated.

No, Brushes shouldn't be able to cause that much trouble.
