>>Has anyone run into any issues running a WPF multi threaded application on a VM? We have an application that is in QA cycle now and one of the testers is having some issues at startup where the startup code is in a background thread. I found some references on the web regarding some known issues surrounding VM's but not real specific. We cannot duplicate this on a non-VM.

I am using a BackgroundWorker in part because it handles the interaction better to the UI thread. I am raising an event within the Worker_ProgressChanged event of the Background worker to raise an event on the application of when it is at specific stages. This does not seem to be happening in as the stage does not get notified. What I have discovered however, is I can now duplicate this on my machine if I run the exe from the directory directly. It does not happen if I run the application from within VS either in debug mode or in release mode.

What would be different specifically if running the exe or running within VS in release mode? I can post some code if it helps to understand what is happening.
