Problems with 3.1.3.8

Hi Ihave the latest version installed for my F1 mill (which is working like a dream) however I have several issues with interface. When I home it (reference it) Z remains with some value for T1. I have no tool numbers available for choosing rather than typing them in MDI. After shutting down and re-referencing it tool dimensions get lost so I have to reposition it. I dont see actual lines of code when loading the program, nor can I edit it (I have to use external editor). Other than that I am a happy chap

Please check with halshow all connections and where the values are changed and report back
