Seems to be an issue deactivating the MyDraw licence after updating to 4.3. Entered my credentials in the about screen login and nothing seems to happen: deactivation buttons remained greyed out and worse the program seems to hang and requires a force quit to get going again. Although oddly, Activity monitor doesn't show it as a hung process. Don't seem to be any hidden modal windows in the app that I can see either (that was another thought I had - a modal window in the background). Suggestions or work arounds? screenshot
