Using KDE3.5 and KDE4

I tried this.
Logging in a tt#: console shows the $HOME/.profile was saved and honored.
The kde4 session seems to honor it.
Konsole comes up and does NOT honor this. Got it to work as /bin/bash -l which 
the documentation says reads ~/.profile. Question is what path is being used 
for menu items?

Clicking a link on say, an email or a bookmark brings up the OLD konqueror--at 
least this one works without a hitch. The new one, well ....
Opera and Dillo are available.

Any, I got wallpaper working (not from the themes which are not honored, it 
seems). Icon sizes will only change as of next login--there is no refresh 
desktop and it is not necessarily refreshed when editing properties. So far, 
pretty nice.
