I don't know, you'll have to check with Ray on that one.  I thought
I had an old copy of the online manual locally, but a quick search
didn't turn it up.  (Maybe I'll look again later.)

Unfortunately, filePro 1.0 didn't have SHOW (row,col), so the 1.0
manual doesn't say anything about it.  :-)

To me, it looks like the 3.0 manual writer documented the bug as
expected behavior, which wasn't caught until recently.  :-)

Yes, if you expected the user to have to press Enter to continue
after the message was displayed, and then did something which cleared
the message, you obviously wouldn't see it.  :-)

However, I wouldn't have expected it to wait, as it wasn't a SHOW "@"
to me.
