X6 is using 98% CPU when idle in print preview

I'm currently working on an XP 32 bit system with AMD Athlon 64 3200+

CorelDraw is displaying a print preview but is otherwise completely idle. It has finished displaying the preview, so it is just waiting for user action but has nothing else to do.

Photopaint in another window was running extruciatingly slow so I checked task manager. CorelDraw.exe was showing to be using 98% of the CPU.

On further investigation, this happens only when the print preview is on the screen. I close the print preview, return to CorelDraw design screen and CPU is 0% when idle. I do another print preview -- 98% CPU again.

I'll try it later on a quad core system, but it seems that print preview should not be hogging the CPU when idle waiting for operator action.
