I have suddenly started getting the following bug trace when exiting an app:

exception class : EAccessViolation
exception message : Access violation at address 004105FC in module 'Viewer.exe'. Read of address 0000052D.

I had a moniflat file link in my app. I have removed it and all references to it, but I am still getting the bug. Any help as to where to start looking appreciated.
