You could do something like this:

on checktool
   if the tool <> "browse" then choose browse tool
   send "checktool" to me in 10 milliseconds
end checktool

Put it into the stacks you don't want altered, and on openstack trigger 
it by issuing a "checktool" command. You'd want to cancel the message 
when the painting stack opens so that the user can choose paint tools. 
Use resumestack handlers to restart the checking when the other stacks 
come to the front.
