I just release an update to the Google NavBar & Toggle Google Homepage Module that works with the new Google Homepage Themes.
Troubleshooting: If the fonts in the navigation become too small, you can fix it by editing the settings for the Toggle Google Module (by clicking on the little down arrow at the top of the module and choosing edit) and choosing a new Link Size.
The recent changes to the Google Home Page framework have taught me never to use relative font sizes when developing inside someone else's framework. The new module now uses fixed font sizes, but the switch causes some weirdness. Fortunately it goes away as soon as you select a new Link Size.
