I'm on the trial now with the latest Rebit 5.0.1035.10670 w/ WXPSP3 32bit.
Clicking on the title bar (& dragging while clicked) to move the Rebit UI around my desktop locks Rebit up. I can't switch to other applications on my desktop that are open behind the UI and/or perform any actions in Rebit itself. CTRL-ALT-DEL is the only way to regain any sort of context. Mouse inputs are not accepted in this state unless you do the 3 finger salute. What gives?
