Welcome to the list of those who have posted and become

The location of the visual mouse clicks is:
C:\Program Files \Adobe\ Adobe Captivate 3\ Gallery\ Mouse\
... but I am sure you already knew that, as you made
reference by filename to one of the files used ...
But if you look in that folder you will not only find the SWF
files, but the FLA (Flash source) files as well. Grab the one(s)
you wish to expand on and open the *.FLA in Flash, then make what
ever change you deem appropriate to your use.
If you do not own Flash or do not have the skills needed to
alter those files, you can use an alternative method, perhaps, to
get what you want. Create a simple animated GIF, and convert it to
a Flash SWF. There are multiple ways this can be done but I hope
those thoughts will help you get started. If all else fails but you
still want a specifically created SWF for the mouse-click visual,
post a note to these forums or to the Flash User forums and offer
to pay someone to do this to your specs. You should find some
takers from the Flash community of users.
