Hi DM,

Recently I moved my BBS to a Windows 7 (32-bit) VM, and occasionally I've noticed an error dialog showing up saying NTVDM.exe has stopped working. It seems to happen with certain DOS doors and not others - One I've been able to consistently reproduce it with is DCT User Chat, and it happens when exiting the door. I doubt many people use that door much, but I've occasionally seen some users run that on my BBS, and I'm wondering if this same error may be happening with some other DOS doors as well.

When exiting DCT User Chat, this information is shown in the NTVDM.exe error dialog:

Recently I moved my BBS to a Windows 7 (32-bit) VM, and occasionally I've noticed an error dialog showing up saying NTVDM.exe has stopped working.

On my BBS machine, I've disabled showing the error dialogs, so users won't get stuck while that error dialog is showing and waiting for my input on my BBS system. So it's not a big issue, but it looked like something going on with sbbsexec.dll.

Okay, I've added to the todo list to take a look at. I'd probably have to install that door to reproduce it and see if it is indeed an issue in sbbsexec.dll.

I get that on some old doors. I've traced it down to a com error with the door. When I get that error, I just remove the door from my system. I've got around it in some cases by loading BNU hot before loading the door, then unloading BNU after the door. Hope that helps

I suppose that's something I could try.. Thanks.

remember that loading a FOSSIL won't do anything at all if the door doesn't do FOSSILs... so if the door doesn't use a FOSSIL and you're not loading it automatically for some other reason, loading it is just wasting resources...

I have the same version. But now I'm unable to reproduce it, so I'll close the bug.
