Cleverly, they called it ‘never combine’ instead of ‘never group’.😉 Combining, in this case, would give your calculators one button to share between the two of them.
I do agree it would be nice to have more options than just these three, though.
Yes, the grouping checkbox from Vista is gone, the combobox is missing a 4th setting that would have provided Win95 behavior: “Never combine and don’t group”. It’s not exactly news that the explorer folks don’t care about old features if they have something “better” to push (Breadcrumbbar over up button, details pane over statusbar and pinning killed the old-school taskbar and later on provided the excuse to kill the start menu)
Uh, this isn’t a fucking bug. You just don’t understand what that option is supposed to do. It has nothing to do with items of the same being or not being grouped right next to each other. It’s only meant to control whether or not multiple windows for the same programs get condensed into only one taskbar item, which you then click and you can choose which one to open from the pop-up menu.
Look at the other option in that “taskbar buttons” setting drop-down menu. “Combine when taskbar is full” … why would they offer THAT option if it has anything to do with modifying the grouping/positioning relative to other instances of the same program?
You should remove this whole entry on your blog. You just misunderstood the purpose.
