I can't say for sure, and I do not speak for Brennan. I think when you have two different browsers open, both trying to control the B2, you're opening yourself up to problems. If one browser (regardless of UI type) says Random, and the other one says Not Random, how is the B2 to know which to obey? It will probably respond to whichever has sent the command most recently. But you do face the problem of the two UIs being out of sync. For true comparison, you need to have only one UI open at a time. (Or, I could be wrong. ;o)
