that is a global wait timer to activate hovering (ie. how much time does the mouse have to stay over the window to activate hoveing)
it is supposed to avoid unwanted window unfolding while in autohide mode...
this is not implemented yet, it will be implemented later, thats why it is disabled
Window Manager is discontinued, for WLM try the new, Enhancer for contact list docking, auto-hide, hide taskbar button, remove button flashing and remember keyboard layout in conversation windows
