Curve editor not working in Corona 1.7 hotfix 4

On one computer it works but on another computer, nothing happens when I press on editor… What could be causing this? (Both run 3dsmax 2018 and Corona 1.7 4)

(I am just wildly guessing but it’s sort of stuff that happens to me in 3dsMax a lot due to many monitors I use)

Does it happen on new scene too ? One which shouldn’t remember position on your main workstation ? Perhaps the Curve editor opens outside of main display and your other PC has different setup ?
But perhaps not.

Both use the same monitors (KVM switch with 2 displays). I am also guessing it opens somewhere else, but how can I reset it?
