Try this:

- Render something.
- Press shift and select an area of the render window with the mouse (for a
  partial render).
- Accept the two dialogs which pop up and let it render the partial image.
- Now press alt-c to go to the command line field.
- Remove the +sc, +sr, +ec and +er options.
- Press enter.

  It will still render the same partial image.

  If you now render again after this (eg. with alt-g), it will then render
ok the whole image.

Argh, shame on me!

  Athlon 1.2GHz, 256MB, Windows 98, POV-Ray beta1.

I can reproduce it. Don't forget to shift-click when doing
the selection.  ;-)

Warp, did you notice this in the Messages window?

Render #1: nothing special
Render #2: Rendering using command line '+sc0.255859 +sr0.140625 +ec0.423828
+er0.307292'.
Render #3: Selected render region is '+sc0.255859 +sr0.140625 +ec0.423828
+er0.307292'.
Render #4: nothing special

It guess that when you render the selected region, you use
the coordinates, then erase them so the next render can be
full-window.

But when you render with the command-line, you don't erase
the coordinates of the selected region, so on the next
render, WinPOV uses them. Then deletes them, of course.

Hope this helps to know you're not the only one. Is the source
code available somewhere, or can we just test the binaries?

BTW, ...

The box is a Pentium-III @ 800 MHz, with only 128 MB RAM.
Yes, "only", because it runs Windows 2000 Professionnal
(French version, service pack 2), and an instance of Oracle
and Java don't help... :-(

As with previous betas, source will not be made available until after the 
final release.  This prevents support problems by preventing unscrupulous
people from disabling the beta timeout and distributing the beta version
as if it were the final release.

Confirmed. This is one is as old as the 3.1 betas. I've given up using
the rubberband select due to the resource release bug (it was fixed in
3.1e, I think) and never got to using it again, but I remember having
a habit of triple-clicking alt-g then.
