[quote=440930:@Alberto De Poo]How can you test that?
I wrote a little app that checked the mouse in a fast timer and compared with the double-click time reported by NSEvent. Xojo correctly responed to double-clicks regardless of the selection lag.
[quote=440930:@Alberto De Poo]I used Notes and Calendar to double click but keep the second click down and the second click activated even if I didn’t release the button. Maybe I need another app that have click-drag to test the behavior.
I suppose there’s no universal rule, but for example, double click a folder in Finder and drag on the second click instead of releasing. It doesn’t open the folder, it does a multi-select drag for me. It’s just more of a “what I’d expect” rather than right or wrong behavior.
