Regarding to "Unhandled Exception" issue during application debug in VS2005

We have received some bug reports that "Unhandled Exception" window appears in development environment during debug of an application which uses Graphics Mill for .NET library in VS2005, whereas in run-time everything is OK.

So after study of new VS2005 features and reading of corresponding information we arrive at a conclusion that it is not an issue. Microsoft have added new feature in debugger which specifies line where an unhandled exception is thrown, but this feature sometimes works wrong and specifies non-existent exceptions. It was discussed on msdn blog.

So to solve this problem you should disable this feature in options of Visual Studio 2005. In Tools->Options->Debugging->General you should find an option which starts with “Treat exceptions crossing...” and turn it off.
