In the meantime, I think disabling the timer > will do what you need although you will still have sluggish graphics while > long-running kernels are active. > Eager to hear the details. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
