okay thanks, what do you mean by ‘tried to adjust the double click speed’ though. I meant the physical time your finger moves but maybe you are using a mouse setting that double clicks with a single button?
Do you recall when this worked for you and what changed on your system since then? For instance, Windows updates, Rhino update, mouse driver updates… If Rhino itself were broken in this regard we’d have heard this from more users I think so I believe it’s system specific and I’m just trying to figure out what the cause is still.
