SWFs start with a white blink when viewed online

This is not a problem I’m familiar with, haven’t seen this with anything else I’ve published online. An example of it is viewable here:


The .swfs that make up this website were originally made by somebody else who has asked me to help them get the site working online the way they intended. The main problem I’m having now is making this white space (that appears briefly in shape of .swf’s dimensions) go away. The flash projects for the swfs do not even have a white background, neither do the HTML documents. Deadline for solving this problem is early tomorrow and I am stumped. This even happens with tiny, 40kb swfs with preloaders (I thought reducing swf sizes, adding preloaders might solve problem somehow)

Help please! :0
