Hi, One of my team memebers tried opening Developer Studio this morning and the screen is blank. She does have the top File menu toolbar and the toolbar directly under it but there's no project area or folders. We did notice her bottom horizontal scroll bar is scrolled all the way to the right but when you try moving it left it just jumps right back to the far right. Does anyone have any suggestions?

Any help? I really hate to uninstall and reinstall for something that may be a simple fix.

How about a screen shot?

On the File Menu go to
Window -> Options -> Explorer

Look over what is checked and not check.
This controls what is displayed in the tree in the Explorer window.
