I'm not anti-social; I'm just NOT user friendly.
I haven't run into this problem, but the layout of your favorites may be unique and you may have discovered a bug. If you don't mind, send me your user.config file in the Local Settings\Application Data\Avian_Waves folder for your version of RD Tabs in your user profile folder (Documents and Settings). Make sure that you disable password saving before you do this -- I don't want any confidential remote desktop passwords floating around the internet!!
