Hi Tim,

Unfortunately, there is no general answer to the question. It completely depends on what 3rd-party controls you are using and what you are doing in your program. There are a million possible reasons for your issue. You have to ask in a Visual Basic newsgroup (or Microsoft) what they recommend to fix this bug.

But what you can try is a "clean" standard Windows 7 installation in a virtual machine (e.g. VMWare). Then install your application to see if you can reproduce the issue.

And this might be a good starting point:


Hope this helps a bit. Good luck
