I remember something similar a few years ago on a client's Windows 3.11
WfWG system. We were working with some pretty large files, also. The font
problem was not the same as you describe. We were seeing the specified
fonts turning into the generic system fonts after running for a while. One
thing that I recall from the application is that it was written very
sloppily by a student and chewed up memory relentlessly. Variables and
structures were unnecessarily copied several times which I'm sure played
havoc with memory, or at least exercised the hell out of it.

Our application was making a lot of use of graphics and widgets.

Sorry, no suggestions other than changing the OS :-)
