I have occasionally seen something like this happen where the program is in the taskbar but the window is nowhere in sight. I remember it distinctly with Outlook, for example. What I have to do is:
1) Click the program's taskbar button
2) Press ALT+SPACE, M
3) Press an arrow key (any will do)
4) Move the mouse
The window generally then is attached to and movable via the mouse pointer. Also, the window generally ends up being minimized to where all you can see is is the upper-left inch of the title bar, or so (but it can be resized from there).
It's kind of weird, but I think it's either a Windows thing, something that happens when games change resolution (and then crash, perhaps?) or both. It doesn't happen that often, but often enough to where I know what to do about it.
A similar thing may have happened to your customer, who then logged off, at which time your program saved its state.
So, I can't tell you what the problem is, but I can tell you that it might not be a Blitz bug.
Anyway, I would just suggest "autocorrecting" obviously bad values after you read them in your config file to workaround the issue.
