Flash Animation works 50/50 in browsers

[TymArtist]

Alright so this is really confusing since the amount of experience I have in integrating Flash with HTML is minimal, but...I created a small .swf to go on the main page of the company I work for. It is encoded in Version 7, which was unnecessary since the player is backwards compatible anyway it seems.

Turns out that it works just fine for about 25%-50% of people that look at it, and not the other. After putting the file to my own website and trying it, and seeing that these people could now see the animation, I have several thoughts and I'd like opinions based on what people have experienced in the past.

Is it...
(a) Another applet on the page is interfering? There are several non-Flash applets that could be causing problems and Javascript that isn't proper due to some companies we have consulting for us...

(b) Our web host doesn't properly support Flash? This doesn't seem logical, but I guess it could happen

Originally I was thinking...
(c) There's a certain way Flash files should be animated and compiled for the web. Maybe I did it improperly? Tried Bottom Up and Top Down, different versions, all that. Same difference.

On one of the computers that had the problem, I reinstalled the Flash player and it worked just fine, although I didn't test it multiple times to see if it still worked after an update.

Any suggestions would be appreciated, and in the mean time I'm gonna do a little more digging. Thanks!

I would guess you ahve some actionscript2 calls in the code which some flash player versions (no the players are not always backward compatible, depends on the makeup of the source file)will not be able to see.

Try exporting for AS1 and AS2 see what difference, if any you get.
