The way I read the 2.2 docs, the wxPD_AUTO_HIDE flag
for wxProgressDialog, if set, causes the dialog to NOT close
when the maximum value is reached.
In my tests (and in the wxPython demo), the opposite seems
to be true: if wxPD_AUTO_HIDE is set, the dialog does
automatically closed. (this seems more intuitive to me
anyway.)
