Just to add to what I said - there is now no tearing with Flip(1), however it seems to be a lot slower to respond in general, for example there is a visible delay when the character turns from the point you input the command, which wasn't there with Flip(). As is often the case fixing one problem creates another... It might just be a case of choosing a lesser evil - which would be the delayed response, as I can't live with the tearing.
