Is there a way to see if Voice Recog is sending Cmds to program?

I am using Voice Activated Commands by www.dwvac.com and their are some keys that I have assigned in FSX that when I use VAC the words are recognized but the key press does not cause FSX to execute the command. If I use the Keyboard to make the command the command is executed. I can even assign different certain key combination's and the command is executed. I want to be able to record the key presses that FSX received from VAC. Is their a utility that I can use to get this information in order to figure out why some key combination's work with VAC and others only with the keyboard?Sincerely,Lynn
