upgrade to artist - pops clicks

I have been running a very stable and clean sounding setup with CE5 for some time now. On the same computer I upgraded to artist 6, no hardware or audio driver changes. I get alot of pops and clicks in artist - especially when I use a slider or other gui control during play back.

If I go back to CE5 everything is still clean. Ideas?

win7 sp1 64 bit
Athalon x2 dual core 1.9ghz
maudio 192 pci audio card - latest driver
6g ram


Are you sure it’s using the correct driver?

Maybe Artist 6 requires a raise of the buffer size?
