EN Plus 6.1.1 on a MBP Retina, 15-inch, Late 2013 running OS X 10.11.1 is extremely slow today. Each character typed takes 1-2 seconds to appear. There are no chats. The new notes is just text. Other notes are mixtures of text with tables and pasted jpg files. They were all there yesterday when EN showed no signs of being slow. EN menu access and switching between notes and notebooks works with no delay. Just typing in new text. Other programs seem to operate just fine and the internet connection shows typical speeds. What can I do to restore the EN function to the level I was accustomed to?
