Those Bugs in Windows 7: Flashy Close Button

All right! Let’s see what kind of bugs Windows 7 has.

Well, I really cannot explain today’s bug I’m about to introduce…It’s really weird.
Want to see? Follow me:

  1. First thing first, make sure your Windows 7 is using an Aero Glass theme, which has the glassy effects on all windows. It’s OK if the transparent effect is not on, though. Anyway, don’t use Windows Basic themes!
  2. Click Start button, find Computer, right click it and click Manage (need administrator privileges).
  3. In the new opened window, click Device Manager on the left. Find a device (anyone is fine), open its Properties window (by double click it).
  4. Move the mouse cursor to the close button on the right-top corner of the Properties window (the red “X” one). Don’t move, see what happened. lol

This Close button will be “Flashy” finally. I called this “Button Seizure”.

In fact, this bug has been existed already since Windows Vista, and it not only exists in Device Manager. I still don’t know the reason, though, that why only some of the dialogs in MMC has this kind of weird things. Is the window procedure of these dialogs more special than standard ones?

(MMC = Microsoft Management Console. Device Manager is actually a management component based on this)
