Really slow editing - help

I'm using PSXE2017 and VS2015 Update3.  I've searched and seen what most have tried and don't see any real solutions posted.  In my case if I'm editing a source that contains modules and interfaces it has started to take 1-2 minutes to respond to each insertion/update.  I can copy and paste only one line before it goes off for over a minute.  I've unchecked the Auto List Members and Parameter setting in the Text editor options.  I've tried to disable intellisense with the options shown in the attached picture.  I've also deleted the .sdf file and made a directory of that name.  Anyone know why it does this and how to make it stop taking so long to allow typing.
