I am using CS5.5 on a brand new mac book pro. Everytime I try to use Indesign the only tool which works is the Hand-grab tool, even when I click on a different tool. I restarted the computer which fixed the issue for about 10mins. I have checked the keyboard and there is no problem there. Is there any other way to fix this?
Most likely a conflict with something else you're running, but please try a couple of diagnostic tests:
Start the Mac with the Shift key held down and work with ID long enough to know if the problem recurs. If it does not, that's pretty conclusive for a conflict with a startup program.
If the problem persists, create a new user and log in on restart using the new user. Again run long enough to know if the problem returns. If it does not, that indicates a user account issue, and trashing the prefs may solve it. See Replace Your Preferences
