Logic Pro X Mixer channels disappear since update
I recently update Logic Pro to 10.4.5 (from 10.4.4) and now when I try and mix using the mixer window (command 2) channel strips disappear sporadically from view. I can be sending a channel to an aux channel and four or five channels disappear. If you close the window and then reopen it, everything is there - until you do an operation.
Anyone have a fix for this? 10.4.4 was perfect.
I'm Mojave 10.14.5 on a brand new iMac 21 inch.
Cheers
Dan.
