That works too.  I ended up switching to SplitterWindows and using
SW.SetSashGravity() to get the auto sash sizing I wanted.  As a bonus,
I'm also able to switch windows with the SplitterWindow variant without
jumping through (many) hoops.

The only place I've made it happen 'reliably' is within the 'search' tab
in PyPE.  Version 2.6.5 has the issue, available here:
http://prdownloads.sourceforge.net/pype/PyPE-2.6.5-src.zip?download ,
the relevant file being plugins/findinfiles.py .

I'm sorry I can't be more specific, I'll see if I can't narrow it down
in the next few days.
