Corridor Target Mapping Dialog Box

[Anonymous]

For some reason, sometimes when I open up the corridor target mapping dialog box within corridor properties, there is nothing to edit.  If I close the drawing and open it back up, it will work at times and sometimes it won't.  It seems to be related to memory usage, but I'm not 100% certain.  Has anybody had this issue?  The subassembly has targets to edit, so that is not the problem.

People have recently been reporting seeing empty dialog boxes: A dialog box will be drawn as an empty rectangle.  One user, I forget who, mentioned it as the "shaking problem".  That is, when it occurs the user clicks and drags on the dialog box title bar.  Moving the dialog box (even just shaking it a few pixels left-and-right) causes the dialog box to redraw. 

I believe it comes down to a video driver issue.  Is this what you are seeing?
