Hi. I'm also now having this problem, now i've updated my OS to High Sierra.
(i preferred Yosemite as everything was faster, but had to due to upgrades).
Indeed, if the application frame requirement/bug can be fixed asap that would be 'welcome'.
With frame is a very cumbersome way of working costing me a lot of time.
