Player getting stuck on objects.

I have a player with physics and some blocks with physics. If my player is standing on a block and I remove gravity, the player gets stuck to the block.

When gravity if off, I move the player around with impulses to simulate rocket movement. This works fine, unless the gravity is shut off while touching a block with physics. If I turn gravity back on, i can jump off the block fine. But if it is off, my impulses don't move the player.

I'll try and get a smaller capx to show the issue.
