Thanks for the quick reply. I was just under the impression that the Amiga software did recognize a PC format CD-R. Guess it's not the same as Cross-DOS (heavy sigh).
As far as the reboot, I am using cntrl A+A, which is why it's so strange. My machine doesn't normally crash, but I noticed it when I was installing software, It tries to reboot, but only a CLI screen comes up. I checked my user-startup, but didn't see anything abnormal.
I guess I can try re-installing the original Startup-Sequence. Thanks again.
