Chris,

I try to limit external calls in batch files as much as possible (exe may not be available on certain OS versions, etc...) Here is a little code that I use for a simple batch file menu with no external calls. Just in case you can't get choice to work.  May not be as elegant as some of Jared's batch files, but it works.

 @echo off 
 
  :MENU 
  cls 
  echo               MENU 
  echo. 
  echo  1.  Option 1 
  echo  2.  Option 2 
  echo. 
  echo  99. Exit 
  echo. 
 
  SET choice= 
  SET option= 
  SET /P choice=Type the number and press Enter: 
  :: The syntax in the next line extracts the substring 
  :: starting at 0 (the beginning) and 1 character long 
  IF NOT '%choice%'=='' SET choice=%choice:~0,2% 
  ECHO. 
  :: /I makes the IF comparison case-insensitive 
  IF /I '%choice%'=='1' SET option=1 
  IF /I '%choice%'=='2' SET option=2 
  IF /I '%choice%'=='99' EXIT 
  IF NOT '%option%'=='' goto CONTINUE 
  ECHO "%choice%" is not valid. Please try again. 
  ECHO. 
  PAUSE > NUL 
  GOTO MENU 
  :CONTINUE 
  Echo Option Entered is '%choice%' 
  echo. 
  pause

Could also be how RC hooks the keyboard.
