same scenario for me too.
however !
today i tried it again and this time the [X] button of the "windowed - display 1" pop-out window closed - however, it worked only in the following the steps below.
my steps were: open RAVE3, click on video in col1/layer1 of demo, goto OUTPUT drop down menu, select "fullscreen - display 1" (by *accident*, i meant to chose "windowed", not enough coffee!), full screen appears, hit ESC key, then hit F1 key and interface reappears (and i can still see "full screen" mode in background since RAVE3 is not in maximize size and i believe i did not disable it, can't remember, sorry), then right back to OUTPUT menu, select "windowed", pop-out window appears, click on [X] button, it closes pop-out window successfully.
but then...
go back to OUTPUT menu, select "windowed" again, pop-out window appears, click on [X] , it does not close it, return to OUTPUT menu, select "disable", then it closes pop-out window.
i will send you the log file.
PS: obviously this is not a stuck-in-quicksand problem with "windowed" since one can disable it from the menu, but thought the detailed steps may help.
keep up the good work
