Hi, I have a G4 iMac running 10.4.11. The lamp shape one. Recently something strange happened to it, it's really driving me nuts!! When I right click, the menu comes up with strange names like N156, N156.1 instead of Open, Open with... I can't figure out what is wrong and how to fix it, can any of you gurus help me? I have repaired the volume with the DVD, I have run OnyX, I have repaired permissions and I have reinstalled 10.4.11 combo updater from Apple, none of them works!! I really hesitate to have to reinstall the 10.4.5 (the disk I have) from scratch because it's a long process to up date to 10.4.11 again and not to mention all my applications and data. Thanks in advance.
