Button behaving weirdly

I have a movie clip, within which exitis a button.

on (release) event
When I click the button, I want flash to get a URL. This works just fine on its own (ie when there are no other events than on (release).

on (rollover) event
When I roll over the button I want the movie clip to play, this works perefectly, again on it own.

However, when I place the two events together, the **on (rollover) **event works but the on (release) event doesn’t. I don’t know why!!!

2 views and no-one figured out what’s wrong with the button? I am really stuck here. Please try to help :wasted:
