Hi PeterPan,
Yeas I agree with you, ICN can be tricky... and these questions asked twice or even more... are quite annoying.
Sometimes I'm wondering if the people doing the configuration use really their software or not!! :-D
Concerning X Window, well except for the installation of WAS which requires X Window, then you can do everything without X... ok, you need to edit lots of XML.
My customer use Xming, Reflection from Hummingbird, etc... and apparently till now, we never had any issues, would like to hear about yours.
Sincerely yours,
Alessandro
