menu-bar and superfish-dropdown-menues behind columns

Hi,
using Drupal 7
Adaptive Themes-Subtheme Pixture Reloaded
Superfish Module 7.x-1.9-beta4
Superfish Library 1.2-beta2

If superfish is set to horizontal and its block is placed into "menu-bar", in Internet Explorer 7 – 9 the dropdown-menus will be displayed behind the div #columns below the menu-bar when they appear.

Solution: in your [subtheme-name].css, set
#menu-bar{ position:static; }

Is it your or Jeff's Issue?

Regards, Mark
