It doesn't happen every time, but occasionally when I click OK to rollover activities, the rollover box stays open. If I click again, it actually rolls over again and creates duplicate activities. I end up having to click OK once, and then clicking cancel several times in order to make the box disappear.
I have version 19.2.146.0, update 4. I'm getting a new computer next week and think I've decided to just bite the bullet and upgrade to v20/v21, so hopefully this is an issue that's been resolved.
