Movieclip button keeps disappearing for some reason.

Question

I created our website using Actionscript 2.0 and on several of our pages there is a drop-down text box that has a "close" button on it, which is just a movieclip located inside the text box movieclip.  For some reason, if you stay on a page for a few minutes the close button disappears.  The hand still shows up when you hover over where it was at and you can still click on it, but it just turns invisible.  I'm not sure what's causing this.  Any suggestions?
The website is:  www.klaesimage.com
Thanks,

My guess is that you have some kind of loop that adjusts the _alpha to brighten it up that is like this:
myButton.onRollover=function(){
this.onEnterFrame=function(){
this._alpha+=10;
And you don't have a conditional to say, "when alpha reaches 100 stop adding more."
So what happes is that the alpha value goes about 100 and when it gets to something like 2^15 it wraps around and becomes an incredibly low negative number. If you wait another few minutes it should eventually get back to positive values!
Of course the best bet would be to put in some conditionals to control that it doesn't go above/below 100/0.
After watching it for a while longer I saw that it does cycle.  I'm not sure why because its alpha should just stay at 100 once it's on that frame, the dissolve up is from a motion tween where the entire contents of the text box go from 0 alpha to 100 alpha over 10 or so frames, but once there on the frame where it stops there shouldn't be any changes to the alpha.
