The isFullscreen() - method is never called when creating the Canvas. The creation of the KuixCanvas in KuixMIDlet.startApp should be:
canvas = new KuixCanvas(this, isFullscreen());
Oh... There seems to be some other troubles with setting the full screen to false also. I tried applying the above fix to KuixMIDlet, but the app is still displayed fullscreen. Don't know what is going on.
Ho right, it was a mistake. Thanks for reporting the bug.
I tired to return false in isFullScreen() and it works fine, on WTK emulator and a Nokia phone.
