Recently I discovered a minor Windows Vista ALT, TAB application switcher bug. Basically, if you press ALT and TAB and then drag the switcher window that shows the application preview, the switcher program only moves the window previews with their container but does not move the icons. Similarly, if you move the icons, the previews and the container will stay in the same place. This is a very obscure bug with no real consequences because the next time you press ALT and TAB everything will be in the right place, but I just thought that it was funny 🙂
Below is a screen shot of this in action.
