Just tried to use Pro 2.3.3 on MacBook Pro 2015, 8G, windows 10. All known patches installed.
I start Pro: it takes 3mins 32 secs (3:32) to even ask me what project I wish to open.
I click the project I want: 6:10 later it finishes drawing a map; not the map I actually want from the project; it isn't done yet though. Task Manager shows the CPU running at 100% for a good 2:00 even after there is no discernable change to the display. I choose the map I actually want display, go and make tee... and it still isn't done 5:00 later.
There are words for software like this. The most polite is unusable.
