I am having this same issue. I double click on an audio/midi event to edit and nothing happens. Also with renaming tracks. I contacted support but they don’t have a solution. They said they would let me know when they have anything.
I am also having the same problem, i can not enter the piano roll with a double click anymore and have had to assign it to a key in order to keep working.
I also cannot change instrument tracks sometimes as it will not highlight when i click on it.
i Cannot load vsti’s sometimes as the list does not appear when i click on it.
This has only happened in the last couple of wks, iv tried re-installing Cubase but does not solve the problem.
Yea, thats the problem and i have recently installed Replica so will try removing it from my project. hope this problem gets resolved cus i love replica!
