Thanks for your patience.
Firbird:
..hmmh..
I can start your builder in IE without changing anything on the pathes with: localhost/sigma21/VisualJS/ProjMan.html.
So I think the path to your js-files is ok. (I cann't test my project because firebird doesn't work for me).
I have the same problem if I build a zip-file from my project and let it run on my localhost. In IE my project works, in firebird not.
Think it is any option declaration in my firebird constellation, but witch

!!!
My problem to set the correct custumstyle. Here my code:
.....
host.block1.append((new linb.UI.MenuBar)
.host(host,"mainmenu")
.setItems([{"id":"id_anw", "caption":"Anwendungen", "sub":[{"id":"standbuch", "caption":"Standbuch", "image":"img/standbuch_16.png"}, {"id":"zuchtbuch", "caption":"Zuchtbuch", "image":"img/zuchtbuch_16.png"}, {"id":"zuchtkalender", "caption":"Zuchtkalender", "image":"img/zuchtkalender_16.png"}, {"id":"trachtkalender", "caption":"Trachtkalender", "image":"img/trachtkalender_16.png"}, {"type":"split"}, {"id":"faktura", "caption":"Faktura", "image":"img/faktura_16.png"}, {"id":"kasse", "caption":"Kasse", "image":"img/kasse_16.png"}, {"id":"lager", "caption":"Lager", "image":"img/lager_16.png"}, {"id":"kalkulation", "caption":"Kalkulation", "image":"img/kalkulation_16.png"}, {"type":"split"}, {"id":"notizen", "caption":"Notizen", "image":"img/notizen_16.png"}, {"id":"termine", "caption":"Termine", "image":"img/termine_16.png"}, {"id":"fahrtenbuch", "caption":"Fahrtenbuch", "image":"img/fahrtenbuch_16.png"}, {"id":"wetterstation", "caption":"Wetterstation", "image":"img/wetterstation_16.png"}]}, {"id":"id_ein", "caption":"Einstellungen", "sub":[{"id":"grundeinstellungen", "caption":"Grundeinstellungen", "image":"img/grundeinstellungen_16.png"}, {"type":"split"}, {"id":"sprachauswahl", "caption":"Sprachauswahl", "image":"img/spracheinstellung_16.png"}]}, {"id":"id_sys", "caption":"System", "sub":[{"id":"datenbank_speichern", "caption":"Datenbank speichern", "image":"img/database_save_16.png"}, {"id":"datenbank_wiederherstellen", "caption":"Datenbank wiederherstellen", "image":"img/database_restore_16.png"}]}])
.setVisibility("visible")
.setDisplay("block")
.setCustomStyle({"KEY":"color:white; font-weight:bold;"}) //<--- what here?

?
.onMenuSelected("_mainmenu_onmenuselected")
);

You wrote:
If the dom id is "linb.UI.PopMenu-ITEM:b:a", that means the template key is "ITEM".
Can you correct my .setCustomStyle line???
I would like to get another font-size in top menu items and all the submenu items
I'm a little bit stupid in understanding the correct syntax.
My ID for the menu is: linb.UI.MenuBar:b:
And by the way: Is it possible to set a smaller font-size for the hole project or switch to another font?
Thanks again for your patiience.
