[SOLVED] Deleting multiple Items on global view

bonjour,

when i try to delete multiple items on global view i get "you are disconnected, please reconnect".

at first i thought i made a mistake by deleting multiple items with different type (milestones, activity) but even wenn i only mark 2 or more entries from the same type, i get everytime the mentioned "error". I tried different browser. deleting the items in the specific view (activities for activities and so on) i can delete 2 or more.

but the global view seems to be buggy and or should have deactivated the multiple choosing.

regards

as i guessed. maybe it is useful to deactivate the function in this view
