And do someone use COMPIZ ( 3D effects etc) as the window manager  to 
KDE/GNome? It's known to cause repainting problems.

I used NVidia on one system and ATI Radeon on two other systems. They
ALL showed the painting bug with MSEgui. None of the systems had Compiz
enabled.

So the problem is NOT just related to NVidia, but ATI too. Hence the
reason Martin and I think it's a bug in X itself and not the drivers
being used.

Why Qt and GTK do not show the problems, I have no clue! I can say that
any Windows application run via WINE did show the same problem I
reported with fpGUI Toolkit. Though with fpGUI I never experienced the
corrupted painting as Martin reported. Instead I experienced line
drawing issues, where end-points did not touch, when they should. So
there were gaps in consecutive line drawing routines.

Regards,
  Graeme.

Add Intel 945 + 960!
With and without Compiz

Maybe better testing from the Ubuntu crew.

The problem actually also occurs when connection to a free NX server, 
using the NX client - then the host makes a similar error in the client 
window.

At me WINE apps don't highlit mouse choice in UltraISO. But it's a 100% WINE 
fault since with older WINE there was a serious failure there  ;)

Name of form.

If I make a new form, lets call it input, it is created like this:

type
  tinputfo = class(tmseform)
  end;
var
  inputfo: tinputfo;

I would prefer it was called inputform (like Delphi), is there a way to 
set MSEGui up to behave like that?

Thanks
Christian
