These have started to appear in my alt-tab (application switcher) in windows:
Rather they would not appear there … I do not quite know what they are.
Also, if Rhino is the active application and I use alt-tab to switch away from Rhino, it seems that the application switcher becomes extra big (often two lines, but the second line is empty). This seems to be some kind of bug. It does not happen if I start in another application.
Thanks
