Wyse PocketCloud Auto Discovery Windows is not readable.

I install Wyse PocketCloud to my Galaxy tab and Wyse PocketCloud Windows Companion (Version 2.1.5) to my windows 7 Ultimate (64 bits) with Norton Internet Security. I already config the fireware (norton Fireware) to allow Wyse PocketCloud widows with full access. I am able to login to my Gmail account via Auto Discovery Setting in both PC and my Galaxy tab. I use "Diagnostic" in the PocketCloud WIndows Companion, it show no issue. However, after I select my PC name in my computer list to connect to the PC from my Galaxy tab, it said that "Could not connect to server". I read in the forum. There is something to do with the Wyse Pocket Clud Auto Discovery setting. I do follow as below.
1. right click to the PocketCloud Windows Companion.
2. Click on Auto Discovery Settings
3. The Wyse PocketCloud Auto Discovery Windows pop up.
However, the windows pop up side is too small. I cannot read all the content in side. I cannot change the windows side or make it full screen. Please help me on this, so I cannot try to solve the "Could not connect to server" issue.

Thank you for your help.
