Hello. my G4iBook/os10.3.3 began keyboard symptoms while in the mail program last 10/05. These were first: no response to the "reply","reply all" both in the mail window and in the main mail tool bar. "forward" and others seemed ok. Then the keyboard started to not respond to "delete", then typing would decrease and finally not accept more that one letter to a line. Ultimately, the "send"key won't respond. Ultimately, the keyboard symptoms migrate into "apple works and text-edit". I have had the apple store people do software repairs and hardware checks and clean reinstalls and archive installs and then give me a brand new G4 iBook with os 10.4 and all the updates. and then the symptoms reappeared on the new machine that night!?. and the apple store people went thru it all again but tried different things, including trashing and rebuilding the mail plist and tried trashing my administrator accounts and rebuilding and trying with their personal accounts in my programs, andever kind of custom reinstall for mail.....and everything they could think of. At least twice during all of these attempts, apple used their hardrives to backup my info: one of these times they unknowingly used a corrupt hard drive! The other times they used my backup for the data transfer. The software and applications I have and use are not advanced: iphoto, itunes, mail, epson perifreals, palm handheld, adobe photoshop elements. The things I have tried to keep saved to my desktop are: my desk top text files and the updated Quicken 14.0.2 data files. I cannot give you an exact play by play nor have I been given every repair report as apple did not generate a customer copy each time. I currently cannot use my mail program. I was told at the apple store, that now they don't know what it could be and that I will have to send it to cupertino for repair. I don't know what to do. Please help me.-- Lisa b.Hammond Production Design & Styling 206.579.4550
