allowEdit option is not working

allowEdit flag is being ignored. Either I set it to true or false, the user can allways delete tags.
On http://tagedit.webwork-albrecht.de it reads:
"allowDelete
Switch on/off deletion of entries. Will be ignored if allowEdit = false
default: true"

So if it is set to true, delete is permitted
If it is set to false, it is ignored, so delete is also permitted? :P
