I don't know if things like the mouseLoc are deprecated but this worked 
as a demonstration, and may do until someone thinks of something better.

The problem appears to be that messages halt (from what I saw) when you 
choose a drawing tool, hence none of the mouse messages (or idle) will 
help. Therefore, we need our own monitor. This is my working demo.

local LmsgID

on mouseUp
   choose line tool
   send "toolMonitor" to me in 500 milliseconds
   put the result into LmsgID
   -- This was a failsafe line used while debugging
   -- send "getOut" to me in 10 seconds
end mouseUp

on toolMonitor
   if within(button "reBrowse",the mouseLoc) then
     send "toolMonitor" to me in 500 milliseconds
     put the result into LmsgID
   end if
end toolMonitor

on getOut
   choose Browse tool
   cancel LmsgID
end getOut
