I have the same problem regarding the Schedule option, and no, a smaller file is not the answer.
I thought the problem could be an solved with an update, but so far I havent found any.
I could try re installing the computer, but this is something I wish to use as a last resort. Re installing the programm itself didnt do much either.
Everything else seems to work fine, but when using the schedule option its just to horrible to work with.
So if anyone could find a solution for this I would be very happy.
thanks in advance,
Les
