Did you follow the direction to change your prefs here: Replace Your Preferences
Which tool do you mean by "pointer"? I suspect you probably mean the Selection tool (the black arrow) but it would help to know for sure.
Yes, I did follow the directions to replace my preferences (multiple times, as the very first time I followed them several days ago it worked, but now everything is messed up and it's NOT working).
The tool I'm referring to is indeed the Selection tool. I asked the tech person on the phone how I should refer to it and she told me "pointer". Both the pure black arrow selection tool, and its neighbor (the outlined arrow) are missing from my toolbar.
This is a real long shot, but try resetting the workspace.
I think, though that you are going to need to uninstall (and check the box to delete the prefs), then run the cleaner tool (CS Cleaner Tool for installation problems | CCM, CS6, CS5.5, CS5, CS4, CS3) and reinstall again.
Bless you! Your longshot worked!!!! Thank you, thank you, thank you!!!
You just got your miracle of the week.
