Let me preface this by saying that I run OS X 10.10, so if this is a bug related to that, just ignore this post!
When I start FoldingText (latest version and dev version), I see the editor window and a white modal window with an activity indicator which refuses to go away. It doesn’t change in any way, just shows the spinner and can’t be moved in any way either. Since it’s a modal window, I also have to force quit FoldingText.
Here is how the window looks like: http://cl.widerwille.com/VxEL
Is that me being stupid and missing something or is it my OS or…?
