#4 Error Drag/Drop files

[Anonymous]

The Demo project gives me an error when I try to
drag/drop files into the listbox. After changing the line

NeroIsoTrack := NeroCreateIsoTrackEx(nil,nil,0);
into
NeroIsoTrack := NeroCreateIsoTrackEx(nil,'bla',0);

i've got not drag/drop errors, but I'm still not able to
burn an Audio CD. (says User aborted ????)

Any suggestions?
