mouseStillDown Not Allowed in Front Script?

[Scott Rossi]

>From a new, empty stack, I loaded the following into a frontscript:

 on mouseStillDown
   put the millisecs
 end mouseStillDown

But nothing appears in the message box when I click in the stack.  Is
mouseStillDown not trappable in a front script?  Does this handler need to
co-exist with mouseDown or something else I'm missing?

Thanks & Regards,
