In Windows Vista, when you're looking at files in a folder, sometimes the layout (the tabs and fields and such) are just plain wrong for the type of folder you're viewing. This bugs the crap out of me so I'm posting it so I won't forget.
You're viewing a folder on your Vista computer when the folder view switches to a different view type. For example; viewing a folder with text files in it will use the Music folder type:
This can be fixed by backing out of the directory you're looking at and right clicking on it's folder and going to properties.
Click on the "Customize" tab and change the folder type template to the proper one:
You can choose between Music Details, Music Icons, Documents, Pictures and Videos and All Items.
Easy; if only it wouldn't change randomly now...
