Since updating to MyDraw 4.3 on the Mac I cannot deactivate the product at all. I go to the about screen, log in and MyDraw appears to stall. Nothing seems to happen at all and the program locks up but not my device. The Deactivate Buttons remain greyed out and there doesn't appear to be a modal dialog box anywhere. Strangely, Activity Monitor doesn't register anything funny like a hung process or excessive CPU usage or the like. I need to Force Quit MyDraw to restore the app to normalcy.  Help!
