[comp.sys.atari.st] gdos / metafiles problem

Hi netlanders !
I develop a program that writes metafiles.

What is necessary to opnwk(Metafile) ?
The problem:
My code always bombed with a buserror and a gemfile.gem 68 bytes long
until I noticed that every example program in every gem book I know of
made an opnvwk on screen before.  I did that to too and it ran. 
Furthermore I found out that the virtual workstation doesn't need to be
open while writing metafiles, it has to be opened once and may be closed
directly afterwards. 

I conclude that this may have something to do with gdos loading drivers
and fonts etc. or at least some sideeffects inside gdos.

Did anybody else see this ?
