You are right, it's ADDQ (i don't have GOOP installed) who systematicaly modify the connector pane.
To solve this:
Go to Tools\G#IDE\Options and Define connector Pane.
ADDQ seem have common configuration between all Labview versions installed, because i have made modification on LV2011 and that automaticaly solve this in LV2009 without any action of me.
Thanks to all for your help.
