I am having the same problem as Travis.
"4) Finally, it seems sometimes that VW takes over the whole computer's resources and grinds a little slower by the minute. I've only had this happen after several hours (more than 4 or 5) of continuous use. Some types of rendering refuse to even try, text changes become excersizes in slow molasses, etc. A general, overal slowing (unlike what you describe). Quitting and re-launching VW doesn't help. Only a system restart fixes this."
This has been really annoying me. Is there anything else we can do? Is this a permission problem, or a memory leak problem. I have also had problems when I have gone to export the drawing to VW 10 or on saving it. (where I am contracting only use VW 10.5 so I have to save as VW 11 and export back to 10) Extremely frustrating as the 'Save' / 'Export' commands can sometimes take minutes to come up.
