I have installed GPG4WIN 2.0.4 on computers at my company. I am using Office
Outlook 2007, Windows XP. Outlook and Kleopatra are running every day.
Each day, after few hours of running, I experienced that gpg4win hangs
connection to the internet. Once I shutdown kleopatra, everything backs to
normal. It happens at each computer, where gpg4win is installed.
