My keyboard shortcuts have all stopped working in CS5.5, in spite of repeated rebooting, etc. I had set up specific shortcuts besides the default ones, and had used them for quite a while before, but for some reason, they just stopped working. I've also pretty much been over all the settings, but haven't found a solution to my problem. Is there some setting I've missed that will bring them back?
Also, I noticed that I cannot change the cursor from the Time Selector Tool. Don't know if the two are related.
