I could help you where to look for settings on a Mac, but not on other platforms, unfortunately. If you are on a Mac, it's in the System Preferences on the Mouse pane. If you are on another system, and you identify it, someone more familiar with that OS might be able to answer. Also, it is my understanding (and I just double-checked with some people a lot more knowledgable than me) that the mouse sends a double-click event . It's a client-side (OS) interpretation of the mouse behavior. Two clicks are not interpreted as a double click by the remote end. That's why you can set the sensitivity with a driver setting. Roll20 would receive a click event or a double-click event, but wouldn't mistake one for the other, regardless of connection quality.
