Hello, for some reason I my preview window is not showing anything. It was working fine until a few hours ago. Any suggestions?
Did you restart Glyphs?
And is there anything selected in the lower section of the view menu?
I did restart glyphs. Here is a screenshot
Did you check the view menu. Deselect everything in the bottom section. There are things like “Show master compatibility”.
I have been playing with view modes for a while. No fix yet 
Also when i manual return and type on the next line glyphs crashes immediately.
I just found the cause of the crash. An update is in the work.
thanks G
fixed!
