Version: (using KDE Devel)
Installed from: Compiled sources
In Konqueror, the "View" menu has two entries called "Enlarge font" and "Shrink font".
In KDE 3 this options just change the font size, but in KDE4 they zoom in/out the whole page, including images, etc.
If this is the intended behaviour, the menu entries in Konqueror from KDE4 should be renamed, IMHO.
