Edit Listview function kills drag'n'drop

[Peter89]

Hi All,

I have 2 Listviews with some columns and want to move Items from the right one to the left. This is working until I've edited one of the left entries via double click function.

I think it has something todo with GUICtrlGetHandle but im not soure about it..

Facts:

Listviews are $searchList & $selectList (drag from searchList to selectList); Edit happens in $selectList

I've copied the related code below..

Thanks and best regards..
