ft-toolbar 2 crashing my script panels

Hi,

I'm using ft-toolbar 2 on a macbook pro, CS6 and mavericks.

I randomly get a problem with toolbar 2 - the panel becomes static and nothing is selectable. If I resize the panel this happens (screengrab).

If I close the panel or reset my workspace it then crashes after effects. Driving me nuts as I cannot re-create the problem - just happens randomly.

I'm using my own buttons also - could this be causing it to happen?

Any one had this problem before?

Cheers,

B
