Yo yo, :mu:
I searched the forums first and couldn’t find anything.
I’m sure you have come across this before, it’s a pain.
I have used flash for years and came across this problem before but can’t remember how I solved the issue.
Finished my flash intro:-
30sec long.
preload of 1 second (56k).
25 frames per second.
swf 63.5k.
The swf plays perfectly until I embed it in a html page where it just runs well, just \*\*\*\* terrible, really slows down (machine specs are not an issue, and the swf plays fine on its own).
Cheers
