Ah, that might help.
<some time later>
Nope. My code just hangs at the time of the kapp.exec(). I've tried it befo=
re=20
and after the KRun, but it just isn't happening for me.

I've attached the whole thing - it reads in a file format that Sony uses fo=
r=20
doing direct reads from a memory stick within a video projector (when you=20
don't have a PC attached). I need this to check my "export from KPresenter"=
=20
code, when its written :-)

If anyone sees what is blatantly wrong, I'd like any feedback...
