I have just bought one of the above cards and set it up on me PC with two monitors. I have used the Desktop Utilities to enable it to treat each monitor as a separate item.
Works lovely, problem is when I drag Hypershade, Hypergraph or Outliner onto the other monitor it wont let you select anything or naviagte aroung the dialogue boxes - they go glitchy.
Anyone else found this and more importantly did you find any fixes? I am gonna try switching the monitors to nView and just doubling the resolution across both screens. So it will be 2048x768 instead of two 1024 x 768.
Tickety boo and ta ta for a bit...
