On load white square appears

when my flash movies load a white ssquare appears while waiting for the swf to load, even for very small movies. Is there a solution to this problem? Putting a preloader before everything seems a bit much?? does anyone else haave this problem. thanks for any assistance.

This is just a guess, but I had some people tell me that if Flash isn’t installed, all that’s on my site is a big white block. Obviously, you have flash, but may want to try to update your player:

The only other thing, if you’re backgrounds of your movies are white, then it’s slow due to loading and you will need a preloader. If your movies have color backgrounds, then I’m not sure.

i’ll try updating, but i’m pretty sure i’ve got the latest. i’m on Mac OSX… and all my backgrounds are black. but thanks for the help. It sort of seems as if Flash is thinking, or is suspended or something.
