Inconsistent Collision Detection

So I have two circular sprites in a physics based game I'm working on. Sometimes collisions between them work as expected. Other times the collision will be detected when there are about 64 pixels between them. I've tried changing the collision masks, but that doesn't seem to change anything.

Any idea what's going on? Thanks!

Are you changing the sprite collision mask or the Physics collision mask? The physics properties can specify Circle.

I'm changing the physics collision mask.

Are you mixing physics with other behaviours (bullet/8 direction/etc) ?

Can you post capx ?

No such mixing.

You are mixing behaviours. You generally can't mix anything with Physics and expect things to work.

No. The Physics behaviour is standalone. It doesn't play well with ANY other motion-based behaviour.
