Currently using Flirc with a Harmony 350 remote to control Windows Media Center, and it works well with one exception.  With a standard WMC remote, when you hit the OK button on a text field, you get an onscreen keyboard.  This doesn't seem to happen with the FLIRC when using the WMC profile.  Is there any way to get FLIRC to emulate this behavior, or any other sort of workaround to get a usable on screen keyboard?

Well, Flirc is a keyboard, so maybe WMC thinks it doesn't need to open an on-screen keyboard, because it got the event from the "real" one (to the system there's no difference between real keyboard event and Flirc events). But this is only a theory. I've never used WMC.
