unhandled exception causes app to fail

Hi,

I have a problem with my visual studio 2008 application. It is written in vb and uses Crystal Reports 2008 v12.2.0.290. I have one client who has intermittent problems where the program closes down with an unhandled exception. What's odd is that I have an unhandled exception handler coded but it doesn't fall into it. The client has 1gb of Ram. I changed her drive swap file from 750k to 4gb and that seemed to help the problem. Help, but not make it go away.

My application is single instance, and other calls to run reports go into that instance. The client has other computers where the problem doesn't happen.

Does anyone have any idea what I can try next? What would cause an unhandled exception that goes around the unhandled exception handler? Is it possible this is caused by trying to call a dll that is no longer responding to my program?

I have run modules comparing a successful run to a failed run on the same computer. I have a list of dll's that were not loaded for the failed run.

BROWSEUI CRYPTUI IERTUTIL NORMALIZ RASAPI32 RASMAN RTUTILS SHDOCVW SYNCOR11 TAPI32 URLMON WININET WINMM.

I am not sure how much help this is as they may simply have not loaded because the programs shut down.

thanks,

Dan
