A while back I posted the news that you can't queue up a notification
while your code is running at interrupt time.

I talked to a guy, Steve Thomas from MicroSoft, who says they've come
up with a work around for this.  It seems the notification manager
makes a reference off of A5 and if it isn't setup properly this leads
to the crash.  This is consistent with the randomness of the crashes
as A5 might be setup OK sometimes.

He says to load A5 from currentA5 before calling the notification
manager and things work OK.

So, if this fix really works, we can actually make us of it for one
of it's major uses.

THANKS Steve!
