Newuser problem .. Faders & Touch screen

Hey everyone .. great community !!
I just started to use OSC and when i try to use faders and knobs, the touch screen scrolls ups and downs and I cant move the fader easily like i used to in Lemur..

Can anyone help me understand how to overcome this?

Thanks in advance...

What's your device and operating system ?

I work on MacOS , Cubase 12 and 24inch ViewSonic touch screen . The thing is that when i use the mouse i can control the faders , its only when i try to use the touch

Thanks for your help!!
