desktop and or finder refresh problem with Tiger upgrade
I just upgraded my 1.5GHz PowerBook G4 from 10.3.9 to 10.4.10 with all the software upgrades and am now having a refresh problem. my desktop/finder keeps refreshing so if I'm typing or in a program I lose my cursor and have to click back into the program. it happens every minute or so with no programs running. I have tried disconnting my external monitor and changed resolutions. I have also reparied permissions. Any other suggestions? I can't find any information online regarding this issue.
