I believe I was trying some erroneous anomolous sequence of steps i probably had no business doing, but it left a little text box on the plot with a watchlist name or something and when I clicked it, up pops a buggy looking request to remove the app from silverlight or remove the silverlight app or something, which I selected thinking the app was just the little unwanted text window.  The next thing I know the TC2000 workspace I was in is gone in a flash and so is the desktop startup icon for it.

So I went back to Worden to get started again, thinking it would reload like the first time, but instead TC2000 started up in my Internet Explorer browser.

The lines appear sharper and crisper to me so I kind of like it, and have tabs right at the top for the this discussion forum and other things is pretty good. But I thought you would want to know what happened.
