I have a WinForm based app that works and exits without any problems as long as a Crystal Report is not previewed. However, when a report is previewed I get the following (From output window):

'DCF.ReconSys.exe': Loaded 'C:\WINDOWS\SYSTEM32\nvwimg.dll', Binary was not built with debug information.
'DCF.ReconSys.exe': Unloaded 'C:\WINDOWS\SYSTEM32\nvwimg.dll'

HEAP[DCF.ReconSys.exe]: Heap block at 05662F78 modified at 05662F92 past requested size of 12
Windows has triggered a breakpoint in DCF.ReconSys.exe.

This may be due to a corruption of the heap, and indicates a bug in DCF.ReconSys.exe or any of the DLLs it has loaded.

The output window may have more diagnostic information

My own code runs through without problems (using breakpoints at all exiting code). The call stack only shows NTDLL.DLL and crpe32.dll.

Any ideas of where to even start? Or how do I unload Crystal Reports when the Reporting features are exited by the user before they exit the application?

TIA,
Richard
