Until receently the fit screen command in full editor performed as advertised for me - ie it zoomed the image to fit the available screen space (about 21% zoom) - however it's suddenly started zooming the image to considerable less than the full screen (around 16%), and I then have to zoom it manually using the scroll wheel or one of the zoom tools. This question has been asked before, but I couldn't get the suggested solution (allowing floating windows in full editor) to work for me. Has anybody any ideas how I can get this useful command to go back to doing what it's supposed to do?
When the editor gets weird, the first thing to do is to delete the preferences. Quit the editor, then restart it while holding down ctrl+alt+shift (command+option+shift on a mac). Keep the keys down till you see a window asking if you want to delete the settings file. You do.
