Disable built-in Progress Window

Hi,

I have a custom language service where I also implemented a custom "progress window" for time-consuming operations. This works well, I can successfully display and hide this window using the IVsThreadedWaitDialog2 interface.

However, if you load or reload a project, Visual Studio itself displays a Progress window stating something like "Loading solution projects...". This window hides my own, and is disturbing. I'd really prefer to use my own window in order to provide the information I want to the user. Is there any way to get rid of this built-in progress window?

Regards,
Max
