Or do you have a script blocker running? The domain http://www.wazeteam.com
needs to be allowed for Toolbox to work.
AHA! Ok, that was it, then. I do have the ScriptSafe extension loaded. I took advantage of your link above there to bring up that page so I could then set the domain to "trusted" status. Brought up the WME and got a message saying that it was initializing the plugin for me, and then no error message.
I look forward to seeing how this tool will help me out now. Thanks for the pointer! And thanks also to bigbear3764 for the replies.
Edit: PS, I just looked at the wazeteam.com site again and noticed a section at the top for login, register, etc. Is that something that I need to do in order to fully utilize the tool?
