I have a message window pop up constantly since updating to Logic X and wonder if anyone knows why it is happening and / or how to shut it off? "This region contains inactive flex markers, which will be deleted if you perform the edit. Are you sure you want to edit the region?" It happens in sessions that I have never turned on Flex globally or on individual tracks. Flex is not on. Having to click this box after every single file length change is a real annoyance but I can't see where track is getting Flex data from. Any advice would be appreciated.
