.... but only under certain (probably unusual) conditions.
Update Drum Replacer to latest in CCC.
Do not update to Sonar G, keep it on Sonar F.
Load a project
CPU rockets sky high and everything grinds to a halt. You must then close Sonar (and wait for 10 minutes or so).
Workaround
Update Sonar or roll back drum replacer.
I updated Sonar, all is well..
If these apps are dependant upon each other then there should be a condition in CCC that does not allow this to happen.
Not sure if anybody wants to try to reproduce this!
Cheers....
