Until now I didn't knew any special issue with SC and software firewalls - until today...
I was having more or less occasional lockups, hangs and disconnections with one of my "clients"....
At first I thought it was about his wireless internet connection and everything, until.... I just somehow noticed that Sygate Personal Firewall was giving security alerts - tray icon was always red after connecton was hanging or even broke and all alerts were about SC.exe launching winvnc.exe etc etc...
Then I knew what was needed to be done - I opened Security options of SPF and disabled driver level protection.
And what you think??? Problem was solved and I didn't experienced even one connection breakdown after that!
This was all!
Even anti-application hijacking option wasn't needed to be disabled!
Once again - this issue is about running Sygate Personal Firewall on customer machine.
With customers having Kerio firewall for example, this problem was never occuring...
It's obviously not a bug, but something, that's good to know for avoiding problems and troubleshooting SC connections.
