Menus in fire fox become "white on pale blue" when launched from ObjectDock

I am running the latest version of OD Plus.   I find that when I launch the latest version of FireFox from the dock, the menus in the browser show a "white on pale blue".

This sounds confusing ... let me start again.

I am running Vista and my desktop theme is Aero.   When I start FireFox from a desktop shortcut and then right click in the middle of a page, the context menu shows black text on a pale background.  When I mouse over a menu entry, a pale blue selector bar shows the entry that I am currently hovering over.  The text of the menu stays black.

When I launch FireFox from OD Plus, everything is the same EXCEPT ... when I hover over a menu entry, the text switches to white.   So I end up with a pale background with a pale blue selector bar with white text ... the combination of which is unreadable.

Again ... launching from the desktop ... all good.   Launching from OD ... bad colors.
