That is good to hear. Thanks.
I don't recall hearing from you that things had started working with 
wxt 3.0.   The last Email I have was with regard to wxt 2.9, admittedly
from quite a while back.  You said then:

Which is fine, but then I never heard that 3.0 did indeed fix things.
I will correct the Release Notes accordingly.

Hmm.  But wxt runs single-threaded on OSX, right?
So this may be another case where the single-threaded configuration
option is sufficient fix, except that on OSX this option is selected
automatically.

Only if you accept that the problem is fixable on gnuplot's end.
That might be true, but if so no one has yet suggested what exactly 
would need to be changed.  The closest is a suspicion that it has
to do with threading.  As I noted, some people have reported that
limiting gnuplot+wxt to a single thread makes things work better.
But for other people it doesn't.  After that the list of suggestions
is empty.

The Windows binaries on SourceForge are provided by volunteers.
If you have a line on a volunteer to provide Mac binaries...
Anyhow, isn't this exactly what fink, macports, and similar projects
exist for?
