Problem transferring focus to another object

I am not exactly sure what you need, but I do something similar. I have a locked field "class" where I want to place one of several text options. I have an option button "class" that I reveal wherever I click the mouse down in the field. That button appears at the mouseLoc and I can then select something from it. The selected text is loaded into the proper line of the field. The button disappears. In the field script:

on mouseDown
   set the loc of btn "class" to the clickLoc
   put  item 2 of the loc of btn "class" into tLoc
   put trunc((tLoc - the top of me) / the textHeight of me) + 1 into tLine
   set the clickedLine of me to tLine --remember the line of recent interest
end mouseDown

on mouseUp
      show btn "class" at the clickLoc
      click at the loc of btn "class"
end mouseUp

And in the option button script:

on menuPick pItemName
   put  the clickedLine of fld "class" into tLine
   put pItemname into line tLine  of fld "class"
   hide me
end menuPick

on mouseRelease
  hide me
end mouseRelease

Works fine.

Try grouping the control and the list field and putting the mousemove handler into the group script?
