Script will not Run unless mouse is moved within Stack

[Camm]

Hello , 


Not sure if I have missed something ? 



On OpenStack 


put "DOG" INTO FLD "Fa1" 
wait 5 seconds 
put "CAT" INTO FLD "Fa2" 
wait 5 seconds 
put "FISH" INTO FLD "Fa3" 


end Openstack 


put CAT and FISH will not work until the mouse if moved inside the mainstack ? 


Best Regards 
Camm
