Hmm... Kcalc seems to not save config changes when you set up an /etc/kde3/kcalcrc with "[$i]" (immutable) at the top. However, you can still MAKE config changes, which last until kcalc is closed. This is KCalc 1.3.1 under KDE 3.0.5. Is there any newer version that disables/removes the 'Configure' button? Thx! -bill! (figured kcalc could be useful *shrug*)
