I started getting this exact symptom after installing 4.06, burned a day and pulled a bunch of hair out (that I cannot spare incidentally

) trying to diagnose. -- All for the better, I guess. As your initial troubleshooting instructions direct, I now have all of my windows upgrades, explorer upgrades, fully virus checked, defragged, and chksdk'd system

...
Then I found this thread, and was about to add my support to Big Daddy that he was not the only one with the problem, when I got to the bottom here with the 4.06a announcement. I checked the several "discs" that I was having trouble with, and sure enough, the disc ID was exactly 12 characters long...
I've installed 4.06a and it seems to have cleared up the issue.
If it helps your programmers to confirm the nature of the bug, this was ONLY happenning on tracks numbered 10 or higher, never 9 or lower...
Thanks much!
