Darn forum! I wrote up a message and attached a log file, and it tells me I can't attach a log file, so as a result I have to retype my message!
Anyway, I captured logging info when the layout didn't show up (nothing showed up - as though CPW wasn't running). By my interpretation of the log file, it tried to show the layout but that's where the logging ended. So I don't know if that's very helpful or not, but I've attached it regardless.
I am doing my testing without my FE running and with CPW running as a normal app, not a service.
I guess next I'll have to uninstall, reinstall, and try again, but I'd like to know what your reaction to the log file is.
I will also test the problem with the menu appearing instead of the layout.
