How do I delete RED VERTICAL LINE in Dorico 5 SE (FREE Version)?between measures 4 & 5?
Thanks in advance for your help. I was sure that I had written down the instructions when I had this problem before, but cannot find them.

Click the line and drag it off the page. When it turns into a line of red dots, release the mouse button and it will disappear.

I finally found out how to get rid of Red Vertical Line in a measure:
SHIFT>OPTIONAL>I. Do this twice. Red line swill disappear the second time you use: SHIFT>OPTIONAL>I
