Has anyone had this happen - is there a workaround?

In Cubase SX3/K2 - Often when editing any SampleTekk piano (moving or duplicating a midi note,) here's a huge "pop." For a moment or two - no sound. Then my system recovers - that is all but reverbs, which are still loaded but don't work until restarted.

Could be the SampleTekk pianos - maybe not.
