>>For #2, I would copy the "bad-roamer" somewhere and try a fresh profile for that user, if you haven't yet. It sounds like that may fix the problem, though at the expense of the settings stored in the old profile. I'd say "worth a troubleshot," though, at least to help isolate the problem.

>Well, it works on the same machine with every other user's profile, and the problem roams with the problem user to other machines. So I think we can already safely conclude that the problem is caused by something in that one user's profile, no? But what? I've searched the registry for the names of the DLL files with the hope that this would give me a clue, but, to my eye at least, there wasn't anything of interest. My only theory, vague as it is, is that my original attempt to bypass the use of InstallShield resulted in some of the DLL's self-registering and the result of that is still lurking somewhere in the user's profile/registry. But this is all well outside of my area of expertise and so I'm not even sure of what to try next....?

Is the error occuring on a Windows 2000 system? Did the user ever log onto an XP system? Windows XP's menu shadows setting cause VFP to C5 when roamed back to a Windows 2000 system. There is a utility from MS to circumvent this, but I don't have the direct path to it. A search of the UT should turn it up.
