I just wanted to add another "testcase". The settings window of the
FontDemo under R5 is a floating window. When you first start it up, the
output window and the settings window look both active (tab is yellow)
and the settings window has some kind of focus. If you click inside the
text control to change the text it will get focus and you can write
away. If you now click into the output window, the settings window will
lose it's active look (tab goes gray). Most controls still work, you can
drag the sliders, hit the checkbox and button - but you cannot get into
the textcontrol anymore. Clicking inside of it has no effect on the
focus, neither does clicking anywhere else inside the settings window.
You have to explicitly click the tab or the border of the settings
window to get to the textcontrol.
This is _very_ confusing and unintuitive. Would be great if we could do without copying this behaviour.
