Rolover issue

Hey, how is everyone doing?

I made a flash site that has 4 buttons, and each o those buttons has its roll over made in another swf (over.swf), so when i roll over each button they call a function inside the over.swf that calls a gotoAndPlay to the adecuate frame and plays the animation.

And if the the user doesn’t click on the button over.swf fades out and returns to the previous one that was visible, otherwise it stays visible.

My problem is that some times when i roll over any button it starts the animation of its roll over but then fades out and loads the previous. As if the mouse had gone out of the button (even though the mouse is still over the button).

Im sorry I didn’t put any code (i don’t have it in this pc, hopefully on Monday I can even show you the page)
