Using Ctrl-Alt-Del

We strongly recommend that this method of shutdown is used only when OS/2 
fails to shutdown in the normal manner, or for some reason the Desktop is 
no longer accessible. 

ZipStream will sense this event and close all open files and abort any 
operations that may have been in progress, before allowing the system to 
stop. 

This ensures the safe and reliable operation of your system. 

Note:  Using Ctrl-Alt-Del may cause files that were queued to be 
compressed, to remain uncompressed.  However no damage to the files should 
occur.
