Hi JFX !! Thank's. Delete UX.exe works well but that not a pretty way to do, isn't it ? Or maybe that the only way ? Anyway I will use it. For the background I will try to remember my DOS and use the startnet.cmd. That not going to be easy, last time I used frequently DOS was on my Amiga 4030 Now I have to find how change the windows background color, set small icons on the menu etc etc .... Best Regards Nexus
