I’m still on High Sierra (10.13) and this happened to me only three hours ago installing QCAD. I switched out to another program for a moment during installation and when I switched back a QCAD installation dialogue box was hidden by the main QCAD installation window. I was able to drag the obscuring window out of the way, but still seems daft not to focus on the interaction blocking window.
