[AS2] Shooting while moving diagonally problem

[WatchCrow]

Bassically I'm trying to make a simple game where you can move in eight directions and shoot. The problem is that when moving diagonally up and left you can't shoot, or if you're already shooting you can't move diagonally up and left. I've seen others with this prblem but it never seems to be resolved.

Here's a .fla I made which shows the problem:

can you re upload in cs3 format?

Yeah, sorry, I assumed it would work anyway for some reason.

EDIT: I eventually solved the problem with more extensive searching. Apperently certain keyboards can't handle using Up + Left + Sace at the same time. I just changes the fire command to 'z'.
