What a datagrid "sees"

As a workaround, you could try a slightly different method..

local sLooping

on mouseleave
    put false into sLooping -- stop the loop when outside the dg
end mouseleave

on mouseEnter
if sLooping is empty then put false into sLooping
if not sLooping then
    send "startloop" to me in 10 millisec
    put true into sLooping
end if
end mouseenter

command startloop
if slooping then
   -- do whatever stuff is needed when pointing at a control here
   -- this just updates the msg box depending on what is being pointed at
   -- since it looks like you're messing with tooltips, you'd probably
   --want to check to see if it has already been set and keep a list of
"set" tooltips
   -- so that you don't reset the same tip every 100 millisec
   -- then in mouseleave one could "unset" based on the list.


  if the mousecontrol is not empty then put the long id of the mousecontrol
/*
 check to see if the mousecontrol is empty in case the mouseleaves while a
loop is still queued. Avoids a potential error.
 would probably need to filter any controls NOT part of the grid for the
same reason.  wouldn't want to change things for a non-grid control
 due to a fast mouse movement.
*/
   send "startloop" to me in 100 millisec
end if
end startloop


Another potential issue I can see happening would be a quick out and in
mouse movement causing dual loops (maybe more?) to run.  So judicious use
of the pendingmessages would likely help.
