A copy of my
other post here about this issue:
I recently did an erase and reinstall to work around the bug in which the QT 7.0.4 update invalidates the QT Pro key...
Anyway, so now I have 10.4.6 on my machine, my system and all the apps are only a few days old. I use Photoshop and Illustrator a lot. There seems to be a problem with the modifier keys in these two apps, particularly the option key. If I use the option key in photoshop with the marquee tool to subtract from a selection, it also forces the selection to center itself around the origin point, instead of from the corner as it normally would, and to be 4x bigger than the preview, making simple selection operations almost impossible. Also, in Illustrator the shift key no longer constrains motion to right angles, and option dragging will display the double pointer, but will not copy as I drag.
Has anyone seen this kind of behavior before? I tried both the US Roman and US Extended (unicode) Input settings under the input tab in the International preference pane....
