Copy behaviour in 3.5 and 3.5.1 has changed from how it was in 3.3.5 - the latest version I ran prior to 3.5.
With copy behaviour I refer to any process where Right Click > Copy or CRTL-C is used.
It feels as if Pro is trying to do too much context sensing and now it introduces hiccups and delays compared to previously.
With everything going on these days I have no idea if this is a bug or an unwanted feature so this Idea is to cover all bases.
