We have two nearly identical Mac computers running Photoshop CS5 Extended with Mac OS X v10.6.8. We are doing film restoration work, cleaning up dirt and scratches with the clone tool on the ANIMATION (TIMELINE) in the Motion Workspace. While we can use the frame advance/back arrow on the bottom of the ANIMATION (TIMELINE) window we find it much faster to use the keyboard arrows for this function. Except that on only one system the keyboard function does not work for advancing to next frame or going back a frame. (The other keyboard functions do work). We have tried swapping keyboards, trashing preferences, repairing permissions and reinstalling CS5 Ext., all to no avail. Does anyone have a suggestion on how to fix?
I have the same problem with the same version of PS5 extended doing image sequence retouching on an identical setup as yours. Reinstalling PS5, fixing permissions etc. all don't help. The arrow keys worked in the past but no more. The arrow keys are a big help. Any advice to put the arrow back in our quiver?
