Xara Photo & Graphics Designer 6 seems to only use 1 core of my quad core processor. First noticed when Xara Xtreme 5.1 was used to open an animated gif (not made in Xtreme). Norton Internet Security 2011 monitors CPU usage and after a while of running the animation in 'Preview', a Norton message popped up saying that 100% CPU was being used. Looking in Task Manager showed the 4 cores of the CPU and sure enough, only 1 was in use and was running at 100%. The graph line on the other 3 cores had hardly a ripple on them.

I wondered if this might still be the case in the new version of Xara so I installed the trial of Xara Photo & Graphics Designer 6 and opened the same animated gif. Still only 1 core being used at near 100%. I had hoped the new version might be able to support multi-cores. Or perhaps it does and something is amiss somewhere?
