Help!!

I'm trying to write a DA in LSC 4.0 and wanted to use a modeless 
dialog as its main window, but I have run into a few problems.
In a DA you have to set the WindowKind field to your refNum so
that the device manager can pass the events concerning the
window to the DA (and handle dragging, closing etc.).
However IsDialogEvent seems to want the WindowKind field set
to dialogKind, and refuses to recognize any events at all.
No sweat me thought, I'll just pass the events right on to 
DialogSelect without asking IsDialogEvent first, this seems
to work as long as I run the damn thing as an application
with the stuff in DA-stuff folder that comes with LSC, but
as soon as I try to run it as a DA everything goes haywire.
If I run it from LSC the DA shell 'unexpectedly quits'
with errors 1,2 or 3. DA handler on the other hand just
quietly leaves along with all DA's that are open at the
time. I do have a couple of userItems in the dialog, and
the error seems to be in the drawProc for one of those, but
why does it work as an application, and not as a DA?

Any help on this would be more than welcome.
P.S. Is it OK for a DA to call SetDAFont?
