I've got Tiger running on a G5 and use FileMaker Pro to copy names of files from and then use the Finder to paste those names onto a graphic file (rename the file). This works as one would expect, for a while, then the finder will only paste the name onto a file icon if you use the mouse and the file/paste command from the taskbar. If you try to use the shortcuts from keyboard or even if you use the keyboard to try and type in a new name, the machine does not respond to the keyboard. Force quitting the Finder appears to cure the problem for a while and then it reappears. Have tried repairing disk perms, ran DiskWarrior, and all seems OK. Any ideas what is causing the problem? TIA, Dana
