How do I stop Internet Explorer from creating new instances?
Is it possible to stop IE from creating a new instance every time it encounters a popup? I am debugging two Silverlight applications at the same time. The first one creates a new popup with the second one. Debugging works great in FireFox because it doesn't create a separate process. But IE creates a new instance, and of course Visual Studio is not tied to the new IE instance.

As far as I know, when opening a new window in IE (either with Javascript or choosing File> New Window) it shouldn't start a new process. The new process is only started when the executable is re-run (for example, from Windows Explorer).
Since MSIE is so closely related to Windows Explorer, but I'm wondering if it has something to do with one of the Windows Explorer settings. Try going to any explorer window, go to Tools> Options, select the View tab and make sure Run Folder Windows in Separate Process is not checked, it might be.
Another possibility in MSIE, Tools> Options, select the Advanced tab to check Reuse Windows to launch shortcuts, although I doubt that would be the case.
