Hanging find process in KDE

[Alan Dayley]

I have fired off the find tool from Konqueror and it has "hung"  I can move 
it's window around the screen and all other open windows and desktops are 
working fine (I am typing this email for example).  But the find tool window 
will not update it's client area or close.  How do I force it to close?

ps -a issued as su in a console window does not show the process so I don't 
know where to issue a kill.
