We recently upgraded to Autodesk 2007 and since the upgrade I have noticed that sometimes when raster images are placed next to each other (i.e., aerials placed on a grid pattern) and the image frames are turned off, there will be a blank void where the frame was. This shows up not only in model and paper space but in the plotted image as well . A coworker mentioned to me today that he had the same issue, only with a wipeout, where the frame around the wipeout was set to invisible, but the area around the wipeout, where the frame had been, was left blank. Is this a known bug of some sort or is there a setting we need to turn on/off?
