I'm no expert on
KDE, but I share your impression.
Konqueror 3.5.10 is a great tool, whereas
Konqueror 4.2.2 appears to be hampered by many shortcomings, some of which seem to be desired by the development team - they've introduced a new app,
Dolphin, to compensate for that. There's a detailed discussion on
KDE's forum; the following post describes many of the problems pretty well:
http://forum.kde.org/kde-4-2-2-the-d....html#pid62817
Again, I'm in no position to join into the discussion, and maybe your problem can be fixed by setting some options, but main problems are inherent in the path the
KDE4 has taken with
Konqueror.
