The titlebar, when using a native window, doesn’t always change when setting the window component’s name.
You can quite easily see it in the new Jucer. If you fire up the actual Jucer’s jucer project, just step through the items in the left panel. SOME of the item names appear in the title bar, and some don’t. It’s quite strange because it seems to always be the same ones that do/don’t [suggesting that it’s actually the content of the string that determines whether it will work or not].
I’m using win7 64, so not sure if this happens in anything else…
