MC not playing on first hover

Question

I have some movieclips that play when you hover over them and rewind when you mouse out. Now I've added a click event to the MCs also and now the first time you hover over them, nothing happens. But the second time works just fine.The MCs that don't have the click event work fine using the same code.
Any Ideas, I've been fighting this for too long now.
Thanks in advance

~all seems to be working fine except rewind will still only rewind one mc at a time. (www.micahanderica.com/mynewwalk)~
