I have noticed that the window menu for most windows look like standard menus, while the window menu for the command processor (cmd.exe) look different. I assumed that cmd.exe was providing custom-made menus, until I started seeing the same type of menu in Chrome.
Here are two images:

Standard Menu

Different Menu
Here are two more images:

Standard Menu in Chrome

Different Menu in Chrome
Right clicking anywhere on a webpage opened in Chrome brings up a menu similar to the "different menu".
What causes these two styles of windows? I am running Windows Vista 32-bit.
Thanks!
By The Way: I also have a Windows 7 64-bit computer. On that computer, cmd.exe's window menu is the "Standard" one, not "Different". It seems Microsoft must have fixed it. I haven't seen how the Chrome menu looks on Win7 64-bit yet.
Edit: I have now figured out what the problem was. The problem was the way the menu items were being added and removed. I found when I disabled AdBlock: Chrome's menus went back to the "Standard" style. So I am asking now, more specifically, what causes this change? What legacy or backwards-compatible code causes this to happen? (I will put it in a new question on StackOverflow if need be.)
