TCP connection blocked when acquisition started in presence of Kerio.
No web browsing possible, etc. 

When trying to quit Kerio, Kerio seem to crash and ask to send a bug report. I
usually decline, and then TCP connection can be established again. The Kerio
icon remains visible in bottom right pannel but does not respond to clicks. 

Stopping wireshark instead of Kerio does not resolve the problem. Wireshark
terminates normally but TCP connections are still blocked. I have to stop Kerio
or reboot to make tcp connection possible again. 

In my configuration Microsoft's firewall is disabled. 

BTW: Wireshark reports CRC errors in outgoing TCP packets. I don't know if this
is related. I wished I could switch this warning off because it is probably
computed in hdw controller and thus not an error.
