I have with the latest 4.1p power (27.01) this message:
This is an automatic ID, so I think this is a bug.
Code:
17:40:44.014:XRP3:WARN:Log:ClassFactory.addGlobalID: ID:'$78l' for object '[Label ID:$78l]' collides with ID of existing object '[Label ID:$78l]'. The pre-existing widget will be destroyed.
