I have a field with a Lookup field rule defined. The lookup is into another database and the popup window position is defined as "Sticky". With each popup, the popup window moves down the screen a bit, so that after a series of lookups, I have to drag the popup window back up toward the top of the screen where the process repeats itself. Has anyone else experienced this? Any clue as to the cause?

Using build 230. Noticed it in the runtime because that's what I'm using for data entry. Don't know if the same occurs in the full version.
