Button mouseover w/prototype

Okay guys, I’ve got a menu with 3 menu items. Each item is a mc. There is a pointer mc that eases to the mc menu item that you mouseover. That was working fine…until I found out that I have to make the menu dumb enough for flash 5. As we know, you can’t assign button events to mc’s unless using flashplayer 6 or higher. So I tried to just drop some invisible buttons over my menu item mc’s and assign the mouseover events to call the prototype in each invisible button. The prototype should then ease the pointer mc to the position of the menu item that I’ve moused over. Problem is that it restarts the playhead back to frame 1 each time I mouse over a button. If someone could take a look and give me some advice I’d appreciate it.
