In vfp9 (and vfp6, vfp7, vfp8) IDE, when the MODIFY window is in edit mode,
it will display an asterisk after file name on window title bar.

it will not display an asterisk after file name on window title bar.
In VFP Advanced IDE and VFP Advanced Runtime, when the MODIFY window is in edit mode,
it will display an asterisk after file name on window title bar.
2. CAUSE:
There are some BUGs in the following code.
