by "pages jump" do you mean your main timeline is changing frames when it should not?
when i test the website (ctrl and enter) the pages jump around without my ordering it to.
If you download the .fla and test it - push the three buttons one after another for about 20 -30 seconds and all of a sudden they jump around without my telling them to....
if you want to wait for someone to download and correct your files, you may or may not get a response.
I never expect any of my posts to be answered - downloads or no downloads - if someone answers them, excellent, if they don't, no problem!
I solved the issue.
The problem was in one of my .swf's - it had the "set-interval" script in various sections of the movie: I just removed all of those and the problem was solved, no more jumping around!
I'm going to enjoy a refreshment now, took me four days to solve that problem....(thanks to Big Resources!)
