How do I configure Corel Draw GSX7 to use more than a single CPU?

Hi,

Fresh installation on a newly built PC of Corel Draw GSX7.

Update 6 installed along with hotfix 1.

However, when doing many different things (no one cause), I am finding performance slow.

Checked in task manager and when Corel Draw is on a go slow, it appears it is only maxing out a single CPU and the system is doing nothing.

PC has Windows 7 x64, SP1 with 24 cores and 128GB RAM.

Any ideas?
