Disabling stylesheet does not update all menu items

[HELBLING Andreas - TDHS]

I would like to dynamically disable certain style sheets in the document.styleSheets collection of a XUL document.

I'm testing with Thunderbird 2.0.0.23 (20090812) and a XUL overlay to messenger.xul and in this overlay I want to disable some CSS style sheets.

So far IT WORKS and the UI is instantly updated EXCEPT that all the <menu> and <menuitem> elements (in the main menu bar) are not updated.
Well, the top-level <menu> elements which are always visible in the menu ARE updated, but all the sub-menus/menu items are not.

Any ideas?

Greez and Thanx
