[Framers] Long Processing Time after a Frame file opens - Latest Frame Versions

[ORAN PETERSEN]

After a file opens and you click on it, it goes into "spin mode" and grinds away for sometimes as long as a minute, depending on file size. Often with two or more files opened, it freezes in this mode and must be killed with the task manager. This also happens when you copy a large section of text. This is particularly a nightmare when you are trying to copy/paste between two files in the same Frame session.
This happens on all computers (Win 10), high-end fully updated computers and Frame version 15.0.6.956
This has been chronic with Frame 14 and 15, all computers. A 200kb file cranked for 25 seconds with Frame "Not Responding" in gray-out mode. It also often shrinks down in window size to about 1 x 2 inches and must be minimized and expanded, and resized to get it back usable
Does anyone know what it is doing, and more importantly, how to stop it?

Thanks
