>Issues I've seen with NT Explorer (hangs, cursor turning into a rectangle, BSODs) have been due to bad video drivers.

We are certain we have the correct, latest video driver. However, the monitor is about 5 years old, and despite both machine and monitor being supposedly HCL, I've totally hosed the NTWS a couple times just by changing a simple video setting. Will try a new machine and monitor eventually (in the budget as we speak), one machine/monitor does not make a good survey sample. We are happy with NT Server/Win9x in the meantime.

Still doesn't explain all the problems, anyway. I've found a way to always reproduce a complete NT hang, even after 4 scratch installs of NT. I go into Add/Remove Programs, select Remove, and I will get an Explorer.exe error every time, and full lockup after 2 or 3 selects of it. No BSOD usually, just full hang/lockup, and full reboot to clear it - very unlike NT, from all I hear and my 5 years or so using NT Server, which has been an extremely good product. Other less-reproducable problems with the NTWS also, but that is the most reproducable disaster.
