Re: positioning probe windows (Cline's approach)

[Rick Riolo]

Ken,
thanks for your time...I know about being busy...

I do have NULL, but that's not important here in that
I do get aProbeDisplay set correctly (if I compile without
that next aProbeDisplay->topLevel).

Its not a link problem, since this is at compile time, not link time.

If you get a chance could you post what you import?

(Actually, this will all be moot soon, as I am just going to
go  the way Sven has hinted at, i.e., make my own patch to patch in the 
getTopLevel method into the relevant source files.
In part I started this thread just to see if there was some
other way to do this that I was missing.)
