I have been using the new Kshowmail in KDE4 ....... thanks to all for getting this ported and included in the repo.
I have had a problem editing the config RC file for the app.
I failed to figure it out until this very minute!
Apparently it opens in Read-Only mode when opened with Kate/Kwrite.
It took me ages to find the solution ...... Kwrite - Tools ... untick Read Only Mode!
Is this normal for this application or is it just something odd about my install?
