Neal, wondering if your Mouse swap revealed any clues, or at least a lack of problems during the subsequent 48 hours of your machine being picked up?
Like many here, have had the video freeze problems first experienced yesterday during heavy iMovie work (bought the machine about four days ago), then w/iMovie active but not in use, I experienced a video freeze up this morning and again (ironically) while reading this mail thread.
Am using blue tooth mightmouse and blue tooth keyboard but via Dlink USB adapter. My machine is 2.8 dual proc 8 core stock 2 GB memory, no 3rd party software or plug ins installed.
Sending my server away, waiting for replacement with nagging fear that it 'may' happen again is not an option for me. I blew > 4 grand which included a 23" cinema display after struggling with a G3 / B&W 350 mhz for years.
Thanks for any info you can share about prospects of a fix.
-Mike
