Stuck in pan mode
It's possible to get stuck with the pan tool ("Hand") somehow - no longer able to select objects.
When this happened, the cursor looked like the Move Tool until left-clicking something then all I could do is pan, and the cursor changed to the hand cursor. I wasn't holding SPACE.
Seemed to happen after either alt+tabbing or clicking a different program window, then returning focus to the Lunacy window.
After manually switching to the Eyedropper Tool then back to the Move Tool, the problem ceased and everything was normal again.
