Buttons in Scrollpane

Hey guys, i was wondering whats up with the scrollpane. Ive got it loading my swf files into it but for sum reason u can press the buttons even if theyre not showing. see below

see the button on the top left how it is darkened, this is the over state, but the mouse isnt actualy on the button, its above the scrollpane area, but its still being selected and is able to be clicked.

Is there anyway around this?
