When opening the fonts gallery in Xara X1 i get 100% CPU usage until i close the fonts gallery, is this a known issue?

The other galleries pull 100% CPU when opened but settle down after 1 or 2 seconds, but the fonts gallery pulls 100% CPU constantly.
I've got 576 fonts installed

System Info:
AMD Athlon 64 3200+ 2.00Ghz
