Scripting the Paint Tool

Hi All,

I'm trying to use the pencil tool to emulate TPC ink input.  (Adding a 
signature to an eForm.)

My requirement is simple: open an area on the screen and capture the 
pencil "script".

According to the Rev Dictionary, this should be easy:

"When using the pencil tool, the cursor is a pencil shape (over images) 
or an arrow (elsewhere).  This tool is used to draw the penColor onto 
an image.

If you try to paint with the pencil on a card that has no images, an 
image the size of the card is created to hold the painting.  If the 
current card already has one or more images, painting outside the image 
has no effect."

So I create an empty image on the card (in a group) and a button 
labeled "Sign" which chooses the pencil.

#1: Once the pencil tool is chosen it never turns to an arrow while 
inside the card.

#2: RR doesn't seem to know my empty image is there and creates a card 
sized image when there are no other images on the card.

#3: I added a gif image to the card, and it seems that I can now only 
write on that image; but the cursor still remains a pencil when it's 
not over an image.

Since the cursor remains pencil, I can't deactivate the cursor by 
clicking on the button meant to return to the browse tool.

I'd appreciate any light anyone could shed on this.  Is the problem 
that my image is empty?, Transparent (?), in a group?

How do I get the arrow cursor to appear?
