If you are obsessed of having GNUBG i can e-mail you an old but VERY STABLE version of it. It has almost the same strength (the newer one is a little stronger) but not the newest great graphics and all the fancy things! Comparing the old with new:
Old strength = 98
New strength = 100
Old total features and graphics = 12
New total features and graphics = 100

The whole package is arounf 12 MB so my e-mail will compain with a dial-up connection but if you want it, i can send it..........?!?!?!??!
