I have tried unistalling and reinstalling Parallels on this 20" iMac already and have the 3188 release. When I try to install a new VM with an XPSP2 disc parallels. I get to the screen that says, "Insert Windows XP installation CD into the CD/DVD-ROM reader and click "Finish" button to proceed." The finish button is flashing blue but does not recognize the click and parallels just sits there. The disc mounts on the Mac desk top but I cannot proceed beyond this point.
