[Pharo-dev] Spec MenuModel not working

Hi, I've encountered a problem with submenus in Spec's MenuModel. When opening a submenu it throws MNU MenuMorph>>activatedFromDockingBar:. It can be reproduced by opening "ApplicationWithToolbar new openWithSpec" and clicking on "File". I'm not familiar with the internals of Morphic so I do not know what the issue is. Also there seems to be some TxApplicationWithToolbar; is TX something I should be aware of? E.g. something that is going to replace Spec or something? Thanks, Peter
