Brent, It sounds like you have found the problem.
Thanks for checking the repaint side of things. That certainly seems to suggest that it is a problem with the internal state rather than merely a painting / invalidation issue as you say. If you open a JIRA ticket, please include the info from your investigation for completeness. Alternatively, find this thread on the Nabble archive and include a link to it. http://apache-pivot-users.399431.n3.nabble.com/ If you are willing and able to fix this yourself, bear in mind that we welcome patch submissions!
