All I know is this has been the case for months on end if it is still the case. Some poor shmo out there is beating his head on the wall because he can't figure out why in a MultiSim help forum he can't send a
MultiSim extension to the forum.
But you see, what it is is he hasn't learned the secret yet: That would make too much sense. It'd make about as much sense as giving teachers military parts when any fool knows students will be using COMMERCIAL parts. So go figure he can't send a MultiSim extension to a MultiSim forum. It's simply par for the course.
