When I right click the name of my project in the projects window and select "Add->Existing Item...", nothing happens. Choosing existing folder brings up the dialog to choose the folder, so that works. Am I doing something wrong? Shouldn't a dialog open asking me to define a location of my existing item? Thanks in advance to anyone who helps.

Okay, this extends to ALL open file dialogs. File->Open, the button on the toolbar, everything. It simply will not bring up an open file dialog.
