When ever I open a file ins sketchup 17 that I have worked on and I want to change something, there seems to be this looooong lag time before I can do anything??

Sketchup 16 seems fine??

Thanks gang!

Jay

Do you have other extensions installed in 2017? Could be an extension that takes a long time to load and/or checking its license. Just an idea.
