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.
Yes, I’m seeing those too. It looks like they’re related to command dialogs and rhino panels. They don’t show when Rhino has just started, but after a command that opens a dialog they appear.
Not all commands with dialogs have this though.
