Which browser are you using? Could it be the IE6? Such a behavior was reported with some
of the editor skins for IE6. We have corrected this behavior with the latest RadControls release Q2 SP1 - build 826, which was released last week.
The MOSS editor version based on this update will appear within a week from now, and you should be OK. For the time being we invite you to test the online demos of the current non-MOSS release. Please let us know if you encounter any problem with this version in your browser.
