Hi Jason,
Sorry I haven't responded to the ticket yet, I have been away from the computer.
Just to add a bit more detail. I have this identical problem on both my iMac and MBP. Are you testing on a MAC machine or Windows? Security Assist is always the last extension installed, even after the FB update I uninstalled SA and FB and then installed the new FB and then SA again afterwards.
It works fine, until SA is installed.
Cheers
Ian
