Jerry,

The problem seems to be that for some reason, the QPrinter device is not
initialised in Landscape mode. Reading the Qt documentation, this cannot
be done on Mac OS X during printing - and unless I misunderstood
something, the Qt driver does that *before* printing. Can you please try
and set up another parameter like the page size, e.g. ./x01c -dev pdfqt
-geometry 500x500 -o test.pdf

I am curious whether this parameter will be applied or not, which will
tell me if only the orientation is unset or if it just sets all the
parameters for the page as defaults.

As for your other issue with refresh, this is hard to diagnose without
having a Mac and doing extensive tests. However, as I plan to redesign
the way the screen is flushed, my future update on this might solve this
issue as a side effect. So I'll get back to you on this subject after
the change.
