I have a problem wioth weightpainting on my machine with an ati 9600 xt 128mb on board.
When i want to paint nothing happens, i.e. the color stays the same while painting…
I have installed the atilogxx.dll and working with windows xp pro and blender 2.36 and 2.37
On my laptop i have a an ati mobility m6 and is working fine (without any patches)
Any help appreciated,
Thanx Twan 
Another thing is:
i copied the file with weightpainting to the computer with the ati radeon (all in wonder, whats in a name) and then i could see the weighpainted areas and they behaved like they should. But i’m not able to change it…
i also tried updating my ati drivers and the use of the atilogxx.dll but still no luck…
Anyone a solution?
Thanx Twan
[edit] I Solved the problem: It has something to do with using double screen. When i expand it over 2 screens weightpainting isnt working. When i use just one it works…[edit]
