thanks for that but this doesn't help.
Have switched to compatibility view in IE before selecting a phone, have reserved a phone (N95), the RDA panel opens with the phone, I have 3/4 seconds during I can navigate, open the menus, have tips when crossing some buttons and then, the application (RDA panel) closes !
If I go back to http://apu.ndhub.net, the phone stays reserved for me.
PS: sorry for the others users if I reserve/cancel the reservation so quickly, I'm making tests !
Sounds strange. What JRE version do you have installed? Are you using 32-bit or 64-bit XP? Did you try with some other browser (Firefox/Opera/Safari)?
