Version:            (using KDE Devel)
Installed from:    Compiled sources

A decision was made recently to disable closing of windows when their window menu box was double-clicked, except in styles which attempt to copy the behavior of another windowing environment.

Regardless of whether the decision was correct (IMHO it is too late to change such behavior since it is inconsistent with prior versions of KDE and will confuse and inconvenience our loyal users as well as those coming over from the Windows environment), the user should have the ability to decide whether or not doubleclick close is enabled.
