What is going on with Cubase 7?

The mix console screen on my multi monitor setup still freezes once or twice a session since I upgraded to 7.5 and it still happens in 7.5.10. The ENTIRE mix console and opened plugins freeze while the project screen and other applications on the other monitors are just fine. To fix it I have to hit F3 (to close) then hit F3 again and it comes back to life. I’ve reported it in the issues section but no feedback. I’ve also given up on the BS that plugins hide behind the mixer. It’s like Steinberg tests using only plain 1 monitor vanilla setups.

Do they test using 2, 3 or 4 monitors (I use 4)?

Do they hook up 3rd party external hardware as part of their testing or just their own hardware?

Unless Steinberg’s adopts a temporary strategy of “STOP ADDING STUFF AND FIX ALL BUGS FIRST”, then I believe this might be my last version of Cubase unless things change… and this is coming from someone who was defending their business practice up until a week ago
