Betton with mouse over graphics, better solution?

I have a button that change color in up, over and down states for a main menu that loads external swfs

On the over phase i want it to show a graphic that shows a preview of the slides. I put the graphic in the over phase but when in the main menu, if i slide my mouse over where the graphic will be, the graphic shows up and is clickable just like the corresponding button.

I dont want the graphic the be clickable.

Please help. Thanks
