Version: (using KDE 4.1.0) Installed from: Debian testing/unstable Packages The "Use fixed font" option in kmail doesn't currently work (Debian kmail 4:4.1.0-2 from experimental). The cursor flickers briefly so apparently the mail is re-displayed, however with the exact same font. (I do have "DejaVu Sans Mono" selected as the fixed width font in the system.) cheers -- vbi
kmail 1.11.1 (Debian 4:4.2.1-1 packages; probably I've also upgraded a lot of other KDE/qt packages in the mean time.) fixes this for me.
