DataGrid mouseDown on scroll bar problem

[quailcreek]

I'm using this script in a data grid. It works fine unless I click the scroll bar of the field before clicking a row of text. Is there a way to prevent this like I capture the dgHeaderControl in line 5?


global grStackName
on mouseDown pMouseBtnNum
dgMouseDown pMouseBtnNum
if pMouseBtnNum is 1 then
if the dgHeaderControl of the target is empty then
put GetDataOfIndex(the dgHilitedIndexes of me, "StackName") into grStackName
end if
end if
end mouseDown
