Since the last update, BandcampDownloader won't start anymore:

That's a preview version, right? I guess Microsoft broke the TaskbarItemInfo. It looks plausible since they seem to have done work on the taskbar in this preview.

If you're on preview, do you have a way to report this issue to Microsoft?

[dertuxmalwieder]

Yes, it is a preview version. I could report this "issue" to Microsoft, but your tool is the only application that does not behave properly as far as I can see - even Cairo Shell does not display any misbehavior, so I could guess that this is not a bug in a strict sense.

[Otiel]

Do you have any other app that is reporting progress on its taskbar icon?

If so, is it working correctly?

[dertuxmalwieder]

Oh, indeed: No more progress reporting in Vivaldi either! Looks like you are right indeed... sorry.

[Otiel]

No worries!

If you wish to report this to Microsoft, send them the following callstack and tell them the bug most probably arises on a Window with TaskbarItemInfo = new TaskbarItemInfo();

FYI, the problem was fixed with an update today.

[Otiel]

Great news, thanks for the info!
