   If one right-clicks on the OS/2 desktop, one of the options   
   presented is "Lockup now", which activates a screen and   
   keyboard lockup program that one can configure via the   
   Desktop Properties notebook.  When activated, a bitmap   
   appears for a while, which then gets replaced by a   
   wandering padlock on an otherwise black background (when   
   the full screen option is selected).   
      
   What I would like to know is this:  what can cause this   
   program to fail?  Every now and then, my office computer   
   gets into a state such that when I select the "Lockup now"   
   item from the desktop context menu, absolutely nothing   
   happens.  The only cure I've found is to reboot, which is   
   something I'd like to avoid, especially when I'm running   
   a long number cruncher in the background.  If the failure   
   mode can be identified, maybe a cure other than rebooting   
   can also be identified.
