Whenever I open the properties dialog box subsequent commands lag 15-20 seconds. For instance, I can open the box (which takes 20 seconds to open), then I can double click into a model space view port. It will take another 20 seconds berfore the crosshairs come up so you can work in this viewport. And that is just one example. Saving the file takes 20 seconds. This happens with a multitude of commands once the properities dialog box is opened. The only way to stop this problem is to close autocad down and reopen it, but once you click on the properties dialog box again all the problems come back.

Anybody have an idea?
