and im made of money too, thanks though, you've given me an idea with your last statement that may fix it

Also, MME32 is the weakest possible driver. Could it be it's just handling the signal so slowly, that when you press "stop" the end of signal is still in process (I don't actually know, if it's possible)?
Are you using the USB mic as your only soundcard or what is acting as your audio interface? Is there one in CTK200 (couldn't find CTK200 description in Casios site nor with Google)?
If you are trying to use both the USB mic (which your computer sees as a soundcard) and, say, your  integrated soundchip, you're very likely to experience problems.

THis could be caused by several things.
 
What sound card and what driver mode are you using?
 
Next, do you have AUTOPUNCH turned on? 
 
I don't think I've heard of this happening with soundcards and drivers at the root of it but a factory (built in) soundcard is the worst possible sound device to use. Knowing what you use would be very helpful.
 
Autopunch is designed to let you punch in and out at specific points to fix things in a track. Is it possible that somehow this is turned on by accident?  If it is, the thing you are describing would be the exact symptom of the punch out point being reached in the track.
 
So... does it cut out at the SAME EXACT place every time?   TRY THIS...... insert a new AUDIO track and set it up to record vocals. Now.... set the time line to where you normally start. Record a vocal take. Does it also stop at the same exact place? If so, check for the auto punch and turn it off then try the recording again.
