Hello Bob,
Using Martin’s idea I put this into a frontScript and it allowed the
“mouseDoubleUp” to get caught. (Make sure you are referencing the correct
dataGrid… this script is specific to "DataGrid 1")
on selectionChanged
if ("DataGrid 1" is in the target) then
wait 5 millisec with messages
else
pass selectionChanged
end if
end selectionChanged
on mouseDoubleUp
answer "mouseDoubleUp"
end mouseDoubleUp
