Text leaving a trail

I made some “zooming text” in flash by creating a movieclip then using actionscript to tell the movie to go to and play that animation when hovered over the mc. I’m noticing that its leaving a trail when the text moves in and out. I was wondering why…it did this when i generated a swf file too.

here is the link www.tsutsumidaphoto.com click on the contact link on the right.

My other question is, is there a way to make the rollover area larger for when the user rolls over the movie clip, sometimes it acts funny because its not big enough. Would you just make an invisible button?

thanks so much, this is driving me crazy!
