Hi John,

Sounds like you are clicking too fast.  If you would like the user to 
be able to click faster then now, you should look up 
"doubleclickinterval" in the TS dictionary.  When I tested your script, 
if I clicked the button slowly (every few seconds) it worked just fine.

You may also simplify your script by exchanging the last two put lines 
with:
delete the last char of field "theWord"
