We are a construction sub conctractor and some of our builders send us plans in the .dwf format. Most computers handle them fine, but I have one that when it opens a file sometimes it randomly puts rectangles where letters should be. If I open the file on a different computer it works fine. I have removed the program and reinstalled, no change. If I have that user print to a PDF file, it prints the rectangles. Again, if I duplicate the same moves on a different computer, it works fine. I thought it might be a monitor setting, but because it prints wierd I think I can rule that out. Any idea what is going on?
