Yes, I more often than not sort on SKU. However, I haven’t been experiencing the serious lag in several days. I believe the culprit is Acronis Backup. I experimented with turning on and off some of the background tasks I had running and the lag seemed to disappear, for now at least, after I disabled Acronis. Unfortunately, now I don’t have regular backup running. BTW, the actual backup was never running at the time I was experiencing the lag. The task was just sitting in the background.
