James hi.

It looks like the same problem as before. Any BLOCK_PC command will 
eat the UNIT_ATTENTION notification. Which is what I was afraid of. 
I was thinking of something like below.

Totally untested, never even booted. It is just to demonstrate the concept.
Please tell me if it is at all desirable and I'll spend some time to see
if it runs, and test it.

Boaz
