In an effort in trying to improve security for adobe flash. You have the ability to set options in a mms.cfg file.
One of those options is the following.
ThirdpartStorage=0
Which basically says do not allow any websites to store swf files if it doesn't match the parent URL header.
After trying this option, I get the spinning wheel at 100% when trying to log on.
After looking at the cache, here is the culprit.
filename = adsapi.swf
URL = http://imasdk.googleapis.com/flash/core/3.233.0/adsapi.swf
Fetches = 28
which doesn't match http://media5.wgt.com
In my opinion we shouldn't allow for any third party storage at all. It appears this swf file controls ads on this website, and in my opinion doesn't allow any flexibility for WGT. Or control of what ads are being displayed on this site.
