Hi, Nathan.
Is your listening on all the time? Is there anything in the VoiceAttack log that says it has recognized anything? The reason I ask is because for the longest time, my wife's computer would do weird stuff... looked like it was zooming in and out. Come to find out she was leaving VoiceAttack on with the headset just sitting on her desk (mic on). VoiceAttack was recognizing some of her words and interacting with her Logitech mouse software.
Also, something that a lot of people do not realize is that you need to make sure any modifier keys (alt/shift/control/windows) are not left in a DOWN state. So, if you have a macro that pushes down the alt key and does not release it, the application is left thinking the alt key is down. I do believe I have a bit of code that runs thru all the modifier keys and makes sure they are UP on exit.
Hope that helps some!
Gary
