Since you have been into the "spanner and socket driver" icon do following:
1.. Go: Configure your Desktop > Help > About KDE > click on "About KDE"
2.. A nice big Window opens and you see clearly something like Platform Version 4.4.4 (KDE 4.4.4)
this is what shows for my system
3.. To be absolutely sure, see big window
in attached picture. The picture shows also two smaller windows.
4.. In the top menu part of the About KDE
window right click and you see the first of the small windows.
5.. Check it is like mine or "shoot it" and attach next post.
6.. In this window move down to Advanced
and when you click the second small
7.. Check again it shows the same as mine if not "shoot it" too and attach.
Remember total attachment is 2 only pictures and combined only 250kB. The exercise is the same as what you have already done for Firefox.
Now I must go and back up my own system.
