I'm completely stumped on an error I'm getting from an FSWrite call, so
I'm posting this note in hope somebody can tell me what's going on.

I'm calling FSWrite on a file which I created in the program, it has
nothing in it (length of 0), the address I'm writing to is from a pointer,
and the length I pass it (how many bytes to write) is about 40K.
It used to return a disk full error after this call, then do strange
things with the cursor and updating of the menu bars.  Now, after moving
the file to a much larger drive (the old one had about 5 megs free), it
gives me a -50 (invalid parameter list) error.  I have no idea what that
means, and I can't see what could possibly be wrong.  the pointer I pass
is valid, as is the file reference (I did a SetFPos with it before), and
the length I pass looks good also.  If anyone can help, please mail me.
