Getting partial datas - markmonitor domains

[Jerkiller]

Hi, I'm using the stable version 4.2.5 of this software.

The issue I found is that I get only partial data of some particular common domains like yahoo.com, google.com, faceboook.com.
Can it make the request to whois.markmonitor.com?

EDIT: in the newest version 5.0 everything is ok.
