Invisible Windows

Hi, I have Photoshop CS2 and am having problems with project windows. Whenever I either try to start a new/open and exisiting document, the window never appear. I can see the image in the navigator, but there is nothing on the workspace, it's just blank, as if I don't have a project open.

It was working fine, has been for months until now. I've tried to search for the project by dragging the photoshop window out, in case it has minimized and been placed down thew bottom right hand corner, but found nothing.

Can anyone help?

Try
Window, Workspace, Reset Palette Locations
