Dvorak Improved - Qwerty is a layout just like Apple's Dvorak - Qwerty ?, except that when you hold down Shift and Command, the proper layout is displayed.

Originally when you held down these keys, it would display the unshifted Qwerty display, regardless of the status of shift (Command = Shift + Command).

Because of this problem, it is impossible to perform keystrokes such as Command + : and Command + ?.
