Your posts are only a few hours old, in the middle of the night in the US - Saturday night to be exact. The chances of someone seeing them and responding with a confirmed bug report so quickly is pretty slim, sorry; but the team will be back online sometime soon and I am sure that they will be able to confirm if they think this is a problem or not. I happen to be in Australia and it’s Sunday afternoon so I saw your post - but I can’t respond with anything about your specific problem as I’m not a Glide user at the moment.
I just ran the example on a EMX development system using Glide V 1.0.3 and Firmware V 4.1.7.0. The current multiple window example may not work with previous Glide versions. What version of Glide are you using?
