Cubase Problems

I’ve transitioned from Reason 11 to Cubase 10 Pro and i have a dozen of problems with this stupid program. First it crashes a lot, second i can’t adjust note length when i click maybe i am missing something it’s either there and i can’t find it or your need to put this INTO THE PROGRAM. Third I constantly open instruments that i am not playing at the moment and edit them while playing other instruments and i wonder wtf is going on and why adjusting these stupid instruments doesn’t do anything, stupid?!?!?!? NEVER SUCH THINGS HAPPENED WITH REASON. AND IT’S FREAKING 100 TIMES MORE DIFFICULT THAN REASON TO WORK WITH WITH ALL THE BUGS AND CRASHES WTF ARE YOU THINKING
