I am using dual screen in win7 with DF and I find when I disconnect the secondary screen where the smart taskbar is, not all the windows appear on the main taskbar again. This has happened to powerpoint windows, adobe acrobat, and other applications.

Anyone else seeing this?

It happens even when I disable the external monitor using windows control panel. Some applications are missing but not all. I can still see them using ALT-TAB.

It seems like Win 7 does not know how to bring back icons but i don't know if this is due to DF or Windows or not. I don't think I had this issue using Ultramon so it leads me to believe that DF is causing some of this.
