Version: tundmatu (using KDE 3.4.91 (beta1, >= 20050910), compiled sources) Compiler: Target: i486-linux-gnu OS: Linux (i686) release 2.6.13-rc6-git9-rt9 There are two places where HTML prefer can be configured in KMail - in the security tab of configuration dialog and from folder menu. Starting with situation both turned off. If I check HTML prefer on from configuration, menu entry will stay same (unchecked), but HTML is already preferred. Menu entry will function not as expected now - if I check it on, HTML is not shown and vice versa.
this works now in KDE 4.3 in a consistent way
