Ok, I tried the .bat thing. I am not sure what is suppose to happen. All I can see is that it made a few .png file in the location you specified. I opened it in fireworks and yes it looks like your page. I went back and tried preview again and it did not work. Just another thing I noticed....when I do click refresh icon next to the choose design...the preview area does flicker like it expanded for a 100th of second with the please wait and then just to the click here statement.
In regards to internet security...I just assumed it was that....but...I totally uninstalled the entire program as well as IE and it still did not work.
We still have the option of throwing it out the window.
