--- Comment #5 from David dav75uk@yahoo.co.uk --- On the threading issues, there is a separate registration tool. I can't remember offhand if chessbase spins that up itself, or uses the same code (I imagine it spins it up since no one is going to run it standalone so there would be no other reason for providing it as a .exe). Maybe it's the two processes together that causes this issue, although there is no problem with the activation dialog (except font issues already raised).
