Movie Testing Issue

I didn’t want to post this in the huge thread about bugs and issues because i don’t know if its a known bug or issue or if its just my computer.

Everytime i test a movie, it doesnt play properly (for instance, i had a script that made a “fountain” effect from the bottom of the swf, but it only played one mc and moved it around, rather than all my particles) until i test the movie again. so what ends up happening is i author my swf, i test it, it doesnt work, i press ctrl + enter again, and it works fine. everytime i test out of the authoring environment it doesnt work the first time but if i dont close the movie and test again, it works the next.

however, the problem doesnt occur if i test it in the flash IDE (it doesnt work properly here) but then i navigate to the swf on my HD and open it, and it works fine. it’s not a huge issue, but it gets pretty tedious and annoying to have to test the movie twice just to see it properly as i’m in the habit of only pressing ctrl + enter once to test, not twice or three times.

is anyone else having this issue or knows how to fix it? Thanks hugely in advance.
