I started experiencing this a couple weeks ago. I open SolidWorks and can see my desktop right through SolidWorks. I can click on File and open a recent part, however I still can't see it. I can't click on any of the desktop icons through the window, so I know its not really the desktop. You can see the file name at the top, so SW really does have the file open. I was on SW2014 when I first experienced it and have since completely removed SW from my machine and loaded 2015 on but to no avail.
Any help would be greatly appreciated.
