Yep, Oracle broke it, and its going to take an update to get things working again. I'll do it either tonight or tomorrow and post a note where when its fixed. The manual install will still work.
The list of all commands is under Help, Command Documentation (Or something like that.. I can't bring up BSW here to check right now).
I'll look into the Chrome issue. I kind of know why it is happening.. The startup file is actually delivered by a .php file. Chrome must be ignoring the mime type and using the extension of the file. I'll see if there's anything that can be done.
