Admin menu + overlay issues and extra scrollbar issue

Issue Summary

I just updated this module to 7.x-3.0-r4 from 7.x-3.0-r3, and I'm still having these issues:

A) Extra white space at top of page appears *after* using drop-down list + overlay: My screenshot example uses Workbench w/overlay.

B) When browsing site's admin menu w/overlay, admin menu sometimes cuts off the tabs.

C) Extra scrollbar and space on right *always* appears because admin menu's width goes past 100%.

These three issues happen with the Bartik theme and Adaptive Theme/Pixture Reloaded subtheme. I thought that some of these issues were supposed to be fixed with the latest release so I'm stumped on what's occurring. I've included a screenshot that shows all three of these issues, and all of them occur for me in the following browser versions:

• Firefox 18
• Internet Explorer 9
• Chrome 24

Another thing I noticed is that although the new search field appears at the top of the page when enabled, it doesn't return any results for me; it just sits there. Besides enabling the Search bar under Config > Admin Menu > Plugins > Enabled components, is there an additional step that I'm missing?

Thanks for any help.
