Audio halts with screen redraw

I’ve got a strange problem.
I mean strange when you look ath the specs of my DAW,

SSD system disk, Quad core Sandy Bridge 2.6 GHz, 7200 audio disks, 12 GB DDR 3 RAM etc.

When I play a stereo file in Wavelab and the cursor reaches the end of the screen, after which a screen redraw happens to show the next part of the wave form, the audio stutters for a brief moment.
In Cubase this never happens.
Is there a setting I have to change in Wavelab?

Cheers,

Try increasing the latency of your audio system.
