Variaudio crashed C6

Another Variaudio crash, within 15 minutes of work, but another kind.

Vorking on vocal, did variaudio edits. Then I applied gate, using Process/Noise Gate. Was notified, that I will loose Variaudio. Said ok, let me see what happens. Did gate fine. Tried to undo… C6 started to flash with window “analyzing audio”, like for 1 second window, then gone, again for 1 second windoww, … This repeated itself some 20 times, then Cubase crashed. Sure enough, it remained running in background, so I had to restart again.

Steinberg, am I doing something wrong? Two crashes in 15 minutes, requiring restart, is a bit much. Please suggest, what do I do?

XP32 SP3, C6.0.2
