[Pharo-project] Problem with window cycling (cmd + narrow)

I think there is a bug in the windows cycling. Or maybe I don't understand it anymore. I remembered I used to press cmd + narrow and the popup raised and then I could choose slowly which windows I wanted. But now, after pressing cmd + left arrow for example, the popup raise, but very quickly disappear. Giving me now time even to look at the current opened windows. I guess this is a bug. What do you think ? I tested in Pharo1.0 rc3 and Pharo 11309. I think this bug is different but related to issue 2289. Cheers Mariano
