I seem to have solved the problem. Although I may have perceived it to be more of a problem than it really was. It seemed like I was having to do a lot more double-clicking than usual to navigate than in KDE3. Now that I've tried it again, KDE4's konqueror seems to act just like KDE3 did with the mouse set to double-click.
One thing that helped - I went into the Menu Editor, and copied the Konqueror shortcut from Internet to System. In the new entry, I changed the command from:
Code:
kfmclient openProfile webbrowsing
to:
Code:
kfmclient openProfile filemanagement
I then saved the menu, went to the shortcut in the System folder, right-clicked on konqueror and added it to Panel. Now I've got a something similar to the old Home icon on the taskbar in KDE3.
