Seriously. I'd love to know. It's been years, and Logos on Mac still regularly launches with a tiny window that needs to be moved and resized. It doesn't matter what you do with layouts. Create a brand new one, re-save the current one after resizing. Doesn't matter. The problem inevitably returns.
Happens even on a clean install, and on different Macs. I recently switched to using Verbum. It came back there also.
