The function "target" returns a string that can be used to identify what object
is getting the system message. In the case of a button getting hit, "the target"
would contain something like "card button id <number>" or "bkgrnd button id
<number>". Check this string for the work button, and you're set.

on mouseEnter
     if the second word of the target is "button" then
         set hilite of the target to true
     end if
end mouseEnter
