Well, what a surprise, loaded PF3 on to the client PC, no other progs, just FSX. Get the message 'FPP error', so it doesn't even get far enough to see about the hot keys.
I've looked at Dave's and others reply about this elsewhere on this forum. The fixes there wouldn't help because:
a) My FP's work ok on the client laptop
&
b) Am unable to update FP3 as I'm using the Demo version.
If my problems are as a result of not being able to update, then the answer must be to buy the program without being able to evaluate it. This hardly seems to be the best way forward.
