Mysterious behaviour of AfDes 1.5.5
Eric Jervis I opened Affinity Designer and found that instead of filling the screen, the interface was only about the size of an A5 page landscape, with the menu at the top and the toolbar at the side completely detached. I remember one strange thing; there was a sidebar a couple of inches wide running down the right hand side of the screen with updates being offered to me, which I clicked away. I tried opening the other version of AfDes., 1.3.5 with exactly the same result, a minuscule interface.
I restarted on the El Capitan drive and the file opened as normal.
