I have a .net application that uses the MapPoint 2006 object model, and it has been rock-solid for a year on XP. After an upgrade to Vista Business, the app started crashing occasionally with the MapPoint internal error pop-up: "MapPoint has stopped working and must close".
Exceptipon Code c0000005
The .net part is not able to handle these errors. Everything is try-catched, and I also have a global handler that is also not handling the error:
AddHandler System.Windows.Forms.Application.ThreadException, AddressOf myEhandler
So the error is thrown inside the mapPoint control. It happens occasionally and randomly so it is impossible to reproduce and even harder to debug. I have turned off ALL firewalls, Defender, UAC is off, etc.
Other than going back to XP, I have run out of ideas. Although it is possible I am the only one in the world that will ever have this problem, I have a feeling that as Vista becomes widely adopted, this thread may get some activity.
