I'm having the same problems on Windows 98. After 20 minutes, the "blue screen of death" appears. No other problems on any other software, and I've used DSL, cable, and dialup - all with the same results.

I've noted a couple of things - first the problem seems to only affect incoming or downloads, not uploads. Second, adjusting the number and speed of up- or downloads has no effect, but just seems to take longer to happen.

I've used Pro, but as soon as this stuff started happening, I removed it, and stayed with basic. Why pay for something that doesn't work? Another note: a much earlier version, I think 4.1 or so, didn't have this problem.
