I tried 4.2 beta recently and found the same problem. It wouldn't
recognise new tcl files as type 'tcl_procs' for example. This is a bug
introduced since 4.1.1. OpenACS is based on 4.2 beta right?
Stephen, ACS 4.2beta was the first 4.x that I used much, so I didn't
even realize that was a bug, but FYI, I avoided it just by naming all
my Tcl files "*-procs.tcl", as that seems to be the convention in the
ACS packages I looked at.
