    Hi all,

    I am posting my response here as well for everyone's benefit. Since Q32009-SP1 release, we had intermittent reports about treenodes remaining as highlighted or even altogether disappearing briefly. Once this issue is seen, restarting the application or closing down other applications did not resolve this issue. However, rebooting the machines seems to have resolved this issue. I don't know what the problem is exactly but atleast there's the most popular workaround :)

    Hi dan harvey,

    Thank you for the question.

    As we are not able to reproduce the issue locally, we cannot provide you with a tested and appropriate workaround. We are still investigating the issue which MP has, namely mouseover paint issues when the machine where RadControls are running is not rebooted for a long period of time. Most of the clients that had such issues, however, actually had issues with their display adapters, because their painting issues were addressed once they updated their video drivers. Therefore, I would strongly recommend you to try updating your video drivers if you have not done it so far.
