Rollout gets stuck on quick mouse movement

The main FLA has buttons linked to external swf files that are nested in a layer inside an html file. When rollover occurs, it opens up corresponding swf file.

Problem is that when a user moves mouse too quickly over the stage, the rollout gets stuck in the last button the mouse posssibly passed by.

I read in another forum that this is an IE specific issue, but I haven’t found any possible solutions. I have also tried increasing the framerate of the FLA file, but had no luck.

Any suggestions would be appreciated.
