Drag and Drop Text into a field

[Peter M. Brigham, MD]

You could set a customprop of the field control on mouseleave:

on mouseleave
   set the uSelChunk of me to the selectedchunk
end mouseleave

then in your dragdrop handler:

put the uSelChunk of fld "targetField" into selCh
put word 2 of selCh into startChar
put word 4 of selCh into endChar
put the clipboardData["text"] into char startChar to endChar of fld "targetField"
