subdomains not worked

[koffu]

Hello!
I have a problem with subdomains - all my queries to subdomain was captured by main domain. Main apache config has defined domain virtualhost and subdomain virtualhost, but in domain virtualhost was main problem -

Code:

ServerName      domain.com
ServerAlias     www.domain.com domain.com *.domain.com vu2004.127.0.0.1

Why developers was made this "feature", which is overlap all domain configuration???

BuildDate = 20100331
Version = 1.0.5 OMEGA
CodeName = Priamos

Is this possible bug? How to fix it in panel scripts, to make apache config normal?
