So I have been having an issue with Image clip that I havent been able to find any help on.  Basically I create an imageclip, invert it so that the middle is hidden.  When I zoom into the drawing, or pan so that the "clip line" is off the screen, that clip stops functioning.  In other words, the image shows up where it is not supposed to be seen.  This making it difficult to edit the drawing.  Any help on this would be greatly appreciated. Also, I don't know if this is related, but once this problem started happening, my viewports started plotting as black squares.  I had printed them previously just fine, and I have bigger drawings that have all the same xrefs, images, and viewport set ups that print just fine. Both of these issues just started recently, a few days after the drawings and clips were created. Thanks.
