FolderDialog Box Crashing Only in Debug Mode VSD2008

Question

I have a folderBrowseDialog box in an application. It has been working for a month. Lately when I run the project from VS 2008 and I click on a button that opens the box the command ShowDialog() runs. The browser box shows up for a second and then I get "Windows encountered a problem box".

Now here is the interest thing, if I compile the project, whether it be in the Debug or Release profile, and navigate to the exe, everything runs fine.

Has anyone have this issue before?

I can post the details of the error report if it helps.

It is a shell dialog, you'll get the shell extensions injected into your process. You probably got a lousy one that is causing the crash. You can see them getting loaded with Project + Properties, Debug tab, tick Enabled unmanaged code debugging. Pay attention to the Output window when you open the dialog, you'll see a line for each DLL getting loaded.

Short from uninstalling the trouble-maker, SysInterals' AutoRuns utility is a good way to disable shell extensions.
