FireWire Express Card does not stay seated in my MacBook Pro. It used to click in and stay there, but now it just keeps popping out. Thanks.

It works fine when it remains inserted in the ExpressCard slot. Works with the software.
I guess it's actually a MacBook Pro problem... Back to the shop.
Thanks for nothing Belkin.
