Switching between workflows laggy and unresponsive at. times

Is anyone else experiencing a lag when trying to click on setup/write/engrave/play/print or switching between individual layouts? It seems to be happening most when using my external monitor. Often I’ll need to click several times

Yes, we have seen this problem with some Mac users. The problem is that due to a bug in the Qt framework, the mouse up message is not always being correctly delivered to Dorico, so the button is depressed but not released. We’re working on this problem at present with the people at Qt. If you’re using “tap to click” in your Trackpad settings, turning this off may help in the meantime.
