Im having some sync problems using MobileMe. If I make a To-do in some random iCal calendar it syncs perfectly, also my iCal event is syncing smooth using MobileMe. But if i create a To-Do in the MobileMe To-Do calendar/Mail To-Do it's not being synced

I have tried to resest sync data on both my macs and also tried to delete all my to-do's but it's not helping.
Any idea what might be wrong
