  It's hard to tell exactly what the original poster is seeing without a 
screenshot, but there are occasional problems with Composition Window 
Managers (such as Compiz) that can produce all-black windows - I think 
it's when the graphics card runs low on memory or something. Google for 
'ubuntu black window problem' for more.

  Try switching off 3d-effects or getting a new video card if you really 
want 3d effects. I've got a Geforce FX 5200 in my Ubuntu box and I don't 
see the black windows that I used to get with my Geforce MX440 card.

  Note this is not an R or Rcmdr problem - it happens with all sorts of 
applications. I used to get it mostly when starting OpenOffice or 
AcrobatReader, or Emacs. It's possible that recent Ubuntu upgrades or 
new graphics card drivers could have fixed it. Are you up to date?

  Or the original problem could be something else!
