For some reason this keeps moving my thumbnail\_mc even when thumbnail\_mc is well away from brake\_right and hit\_right. When I move the mouse back and forth onto and off one of the thumbnails it sorta hops to the left ten pixels every time I hover over it again. Please help me figure this out! If you need the .fla just let me know and I’ll upload it somewhere.

function thumbNailScroller(total) {  
// thumbnail code!  
this.createEmptyMovieClip(“tscroller”, 1000);  
scroll\_speed = 10;  
brakeSpeed = 10;  
tscroller.onEnterFrame = function() {  
if (hit\_right.hitTest(this.\_xmouse, this.\_ymouse) && thumbnail\_mc.hitTest(brake\_right)) {  
thumbnail\_mc.\_x -= scroll\_speed;  
} else {  
thumbnail\_mc.\_x -= brakeSpeed;  
brakeSpeed = brakeSpeed-1;  
if (brakeSpeed=0) {  
delete tscroller.onEnterFrame;  
}  
}  
if (hit\_left.hitTest(this.\_xmouse, this.\_ymouse) && thumbnail\_mc.hitTest(brake\_left)) {  
thumbnail\_mc.\_x += scroll\_speed;  
} else {  
thumbnail\_mc.\_x += brakeSpeed;  
brakeSpeed = brakeSpeed-2;  
if (brakeSpeed=0) {  
delete tscroller.onEnterFrame;  
}  
}  
};  
}
