SYMPTOMS
When you start a full-screen MS-DOS-based program, the program starts but may only be visible on the upper half of the screen, and the lower half of the screen may remain blank. Note that this issue only occurs under the following conditions:
 * You did not upgrade to Windows 2000, but installed Windows 2000 to a computer without a previous operating system.
 * You started the MS-DOS-based program in a full screen instead of pressing ALT+ENTER to change from a window to full screen.



CAUSE
This issue can occur because the height value for the screen buffer that is running in a console window in Windows 2000 is 50 lines, but in Microsoft Windows NT it is 25 lines. Because of this, MS-DOS-based programs that are set to start in a full screen use 50 lines, causing the program to reside in the top 25 lines and leaving the lower 25 lines blank.



RESOLUTION
To work around this issue:
 * 1) Start your MS-DOS-based program in a full screen, and then press ALT+ENTER to display the program in a window.
 * 2) Right-click the CMD icon, and then click Properties.
 * 3) Click the Layout tab, and then lower the height value for both your Screen Buffer Size and Window Size from 50 to 25.
 * 4) Click OK, and then save the changes for future use.
