One for whoever maintains ResEdit.

Having just downloaded ResEdit1.3d1 (which identifies itself as 1.2b4.1 when
you use option-command-About ResEdit), I have a minor whinge.

Using previous 1.2 versions, I was able to include custom CDEFs in resource
files, point CNTL resources at them, point DITLs at the CNTL and ResEdit would
handle DLOGs all fine, calling my CDEF to display the controls, etc.
However, now (with 1.3d1) I get address errors when I try to open the DLOG.  

Using TMONs discipline, I can see that somewhere in FindDItem(), NewDialog is
doing a NewControl() followed by a MoveControl() without checking that the
control was created ok. Examining the code with TMON would appear to show
that ResEdit is doing UseResFile(appRefNum) followed by a _NewDialog(), then
a UseResFile() afterwards so I presume the problem is that the CDEF is not
available and NewControl() fails accordingly.

I blame the ROM but thats irrelevant.  I would really like my CDEFs to work
again.  Why did ResEdit suddenly decide not to allow CDEFs in the current
resource file to be used?  And can this feature be put back?

Yes, I know I can paste the CDEF into ResEdit.  I don't want to because I am
developing the CDEF as well as the application that is using it at the same
time and both are relatively volatile.  Besides, god knows what internal twists
ResEdit will get into if I start adding CDEFS to itself with itself.

Oh, a (slightly) related issue.  Has anyone had the hassle using ResEdit & LSC
under MultiFinder where ResEdit doesn't close a file properly and LSC barfs on
trying to write its linked output into the file.

Thanx in advance,   Rob
