Why do I get a red background before content loads?

Just before the flash player loads it's contents, I get a red background for maybe like half a second or so.
I'm quite experienced in html programming, and I'm unable to figure out whats going on, so I'm suspecting it's the flash component itself that's generating this.

Any clues to what's going on? I've searched high and low in the config and in the forums, but I'm unable to figure this one out.

Sure... here is an example:

And, yes, I got that line of code from you actually It was included in one of the templates in an earlier krpano Tools version
