[Wine] Baldur's gate II - 'rest' function problem

[Mceepo]

I run Ubuntu 10.4 and Wine 1.2

Everything works fine, I had no problems with installation but during the tutorial (I haven't tried elsewhere) when learning about casting spells I am told to click 'rest' but this results in a blank, black screen. 

I have tried running with and without 3D acceleration as well as in 16bit and 32bit modes but it doesn't seem to make any difference.
