After I open Acrobat Reader, load a file close it and exit, I get an crash message window: "Spool32" (stack error in spoolss.dll). Thereafter, in Configuration/Printeres all my printer icons are gone and I have to reboot the computer to fix the mess. This has been happening to me with both versions 4 and 5 of the Reader and on 2 of my office computers, but only on those 2!

Help will be appreciated...
