When working over VNC, often Tools cannot be chosen
When I connect to my Mac over macOS-VNC, I can use everything as needed. Unfortunately sometimes Indesign shows the hand and lets me use only the hand to move the page, although I clicked the Arrow e.g. and it is selected. I the cannot select Text, change sizes of boxes etc. The only remedy is to reconnect via VNC, but not every time that works. I do not have this with any other program than indesign, so I am starting my journey of finding the root of this here.
