Firewall Blocking Issue

```
When a firewall, such as ZoneAlarm blocks internet access, the portable edition 
will hang for a minute or two before displaying a notice that it could not 
connect to a server to check for updates.  After this, the main interface is 
seen.

OS: Windows XP Pro Service Pack 3
WDCC v1.8.3
