The one thing you can’t complain about, however, is how nice and easy KDE’s system settings are. Just open them up via the “start” menu, and find the Keyboard & Mouse icon.

Click on “Mouse” in the left hand menu, and then choose “Double-click to open files and folders – select icons on first click”. 

Now you can safely click on icons again! 

Why this isn’t the default in KDE when it is in every other operating system, I’ll never know.
