serialization problem in .net is solved

not possible to serialize the dictionary objects and nullable types in the form of xml, ie xmlserialization, this has been resolved by new xmlformatter class in .net 3.0.
so in .net 3.0 able to serialize generic types and nullable types. not tested actually. if any one tested it then tell me.
thanks

installing mozilla thunderbird in windows xp and norton antivirus

when you install any internet aware applications, like news agreegaters, the norton antivirus does not allow them to access the internet, so these applications does not tell you that norton firewall is stoping the access, so manually created a firewall rule stating that allow access to thunderbird to use internet.

the problem is for some applications norton firewall tells that program is accessing the internet -"do you want to allow it or block it". why it is not informing for thunderbird.
