The default mouse click behavior was changed to double-click a long time ago in this patch:

http://www.trinitydesktop.org/patches/1284792137:5ec667408632981bb995a8af480429469d19d756.diff

Checking the affected 3.5.13 header file shows the change is good with no regressions.

I also have my own default global $PREFIX/share/config/kdeglobals file that has SingleClick=false. The file does get installed and the setting is the same.

When I create a new profile through the KPersonalizer wizard the default becomes single-click.

When I skip the KPersonalizer wizard then the default is double-click.

Therefore something in the KPersonalizer process is overriding the system defaults.

Would somebody please confirm this behavior?

Thanks.
