Fix for Script Error......
You can go to Mozilla and add YesScript..
When I open GW I just click on the YesScript icon and it turns off script.
I also had a hard time finding the icon once I downloaded it.
So here is where you find it ....
"While YesScript goes into the add-on bar by default, you can customize it like any other toolbar button. Just go View, Toolbars, Customize, then you can drag it to wherever you like."
