How the heck

can you use the slider on the right of the mixer? Every time I try to move it up pops a box to enable control room. Very frustrating!

Doesn’t seem to be a problem on my 23" monitor…Are you on a small screen.

But in general these scroll bars are a bit thin…style over substance.

I have a 4K 23" screen. The problem is the popup appears too quickly, before I can move the slider. I cannot find a way of turning it off either
