While browsing and watching some movies/videos right over at YouTube I found some IMO weird behavior by DisplayFusion which shows the Flash icon for the whole browser-group.

I could reproduce this behavior in Google Chrome v19.0.1049.3 and Internet Explorer 9

Windows 7 taskbar:


DisplayFusion 3.5 Beta 5 taskbar:

I need to bump this thread again :S

I noticed the same behavior in Windows Live Mail, or more general: In any application that opens a new window with a different Window Icon than the application and is the one that has the focus.

So if you just open Windows Live Mail you'll see the WLM Icon in your taskbar, if you then go ahead and open a (new) mail, the taskbar icon will switch to an envelope. Now, if you select the main window again, the icon will switch again - you can repeat this process as long as you want.

Windows 7 doesn't change/update the taskbar icon depending on which icon is selected/opened, it just stays to the application main icon.

It definitely works as expected! Good job!
