Hmm.. that sounded like a good explanation! And I feel bad having to tell you 
it did not fix it :-((   (tested with 1.1.13)

On some channel switches it does not happen, on some it does, and every once 
in a while it will flash twice instead of once.

Though the patch probably does help, the flash is not yet eliminated for me. I 
hope other people have more positive reports :-)

Thank you very much for such a quick reply though!
Regards,
Dennis
