See a very strange thing (think since I installed 9.1.7): On a several pretty small/simple sessions I see intermittent the CPU load going to 100% on one of the 8 cores, sometimes to the point that the audio crackles.
But this only happens when Arange window is visible, when I select the mixer window the load stays very low (as expected). When a Arange window is opened on top of the mixer (CMD-1) the load on one CPU suddenly starts to 'pulse'... Anybody else sees this?
Thanks in advance.
PS: No AU instruments are in those sessions that could be in 'Live mode'...
