This is not a "click".  This is a "click & hold" and is used with "drag" 
features.
A "click" is a press & release.

If you do not already have focus on the window you are attempting to 
drag it will not select it for dragging.  You will need to first "click" 
to set the focus, then "drag" to do the move..  Your descriptionn fits 
the situation where the title bar is not the window with focus.

Your description is symptoms I have seen on a lot of different platforms 
when the window where I do the "drag" does not have the focus so the 
action does a "select" on the desktop or other window instead and draws 
a box to outline the region selected by moving the mouse.
