Yes, it still does! So it really is broken...
I think I need to investigate into the internals of how explorer determines its icons. Actually, you may know better.
If you give me an exe to run, and have it dump out output from those buttons, maybe we can see what explorer is thinking this icon is.
Im sure you have the code that you could break out into some test app and have it dump out stats about the icons, so Ill run anything you want, and send you the info. Maybe then we could figure out what DF is doing to this icon, to make explorer mess it up / treat it differenty.
I have a much better video demo for you now. Watch this:

(its easier to see my text in notepad, if you select "Large Player" and "480p")
If I get time, I almost want to just try this on a VM, AND also on a test Win7 x64 HDD partition for a clean system, and see if the same behavior is exhibited.
Just as a sanity check, here are all of explorer.exe's loaded modules (from Process Hacker), sorted by Company Name (the 2nd column/item)

But its nothing that should be causing this... (most are Microsoft, obviously, but the ones that are not, shouldn't have anything to do with the taskbar).
Right now, I think the best thing to try would be to get a detailed "internal" list of what explorer.exe things this "icon" is.
I think this could be easily done from some code from you that you could compile into a binary, and send over, and ill run it, and send (and look at), the results... see if this is truly different.
You can hack up my explorer.exe's memory all you want
, esp if it leads to figuring this out!
