Description tilleyrw 2006-08-18 02:21:15 UTC

Version:            (using KDE KDE 3.5.4)
Installed from:    Ubuntu Packages

When viewing the page "http://www.oswd.org/design/preview/id/2993" in Firefox 1.5, the entire area on the left side of the window (the Pages/Category/Meta links list) is correctly rendered in light green.  When :hover'ing over a line, the background of the line switches to a lighter green.

When this same page is viewed in Konqueror, the heading "Pages/Category/Meta" areas are colored light green.  However, each link line has a yellow background and when :hover'ed over becomes almost white in color.

This is an extremely noticeable CSS-rendering bug that should be easily fixable.

Hope this helps, Bob

Still valid in 4.1.1
