I'm running Affinity Designer 1.5.5 on a Macbook OSX 10.12.6. My character and paragraph popup menus no longer work. Not sure when this started, but it is probably within the last month. I have a document with a text frame full of text. I select the frame text tool and go into the text box, and select all the text in it. Then I click on "Character" tab at upper right on bottom edge of ribbon at top of screen. Nothing happens. Same with the Paragraph tab. My paragraph is indented and I want to remove the indent, but I can't see how to do it with the character pop-up missing. I restarted my computer to see if that would make a difference, but it did not.
