Describe the bug
Three-finger click doesn't do anything. It is recognized in Live View, which (most of the time) identifies the action (CMD-Click), but it has no effect in applications. I have checked the trackpad preferences, and three-finger click is not selected for anything.
I double-checked, and three-finger drag is off. It's set up to trigger CMD-click in all applications, but I've only tried it in Safari and Mail.
In Live View, sometimes it shows "CMD(⌘)+Click" in response to "3 Finger Tap," and other times it just shows the time-stamp, "3 Finger Tap," and the message "Only gestures you have already set up in BTT will be recognized correctly." In any event, the CMD-click action doesn't seem to happen.
When I turn on the HUD Overlay, sometimes it appears, and sometimes it doesn't (even though Live View recognizes "3 Finger Tap")—but again, in any event, the CMD-click action doesn't seem to happen.
What is weird is, when I close the BTT window, I get better results in Safari: Sometimes the HUD appears and CMD-click works! But only sometimes: mostly nothing happens.
