Your selected bars stay selected
Clicking somewhere else on the page no longer clears the bars you picked in the score, or the bar where playback stopped.
A click anywhere outside the score, on the page's header, a panel, the space beside the score, used to clear the bars you had selected and the lit bar where playback stopped. A loop you had just set up with Shift+click could vanish that way.
Now they stay until you pick other bars in the score. A click on a bar still picks that bar, and Shift+click still picks a range.
