I'm still having random issues with this. Seems like half the time when I go in to edit/create a call to a method in my class that the documentation in the tooltip is gone. Sometimes I can switch tabs or save or something and they come back, but usually I have to restart B4A. It isn't a matter of editing the class or special chars anymore either- Class hasn't been touched and no char issues...and they do load initially. When exactly do they get created or recreated/what event triggers their creation (or could be causing their removal)? If there was some action I could take to cause it to recreate them and show them or something not to do to prevent them going away it would be much better than restarting B4A.
