Welcome Cutslick.
Wish I could help you. Have you tried using Ray Adams' ATI Tray tools instead of Catalyst Control Center? It behaves slightly differently and might be worth a try even though there's honestly not much chance it'll solve your problem.
Thanks Nicki, I'll take a look at that and see if it offers any possibilities.
Thanks also for the welcome
Edit:
Well I tried ATI tray tools and it looked like there were possibilities there in that the program would apparently recognise start up of an application and adjust settings in a preset profile to suit. The problem however was that 'crossfire' doesn't feature in the preset profile menu and also in the separate hardware tab for enabling 'crossfire' it came up as unsupported.
Odd really because it is there to be enabled or disabled in the vanilla Catalyst Control Center.
Thanks anyway Nikki it was certainly worth a try
