I would like the user to be able to choose "Unblock" on the security alert
dialog when my application attempts to send a UDP packet for the first time. 
However, the securlty alert dialog does not appear.  I have to tell the user
(when running the app for the first time) to manually add my app to the
exceptions list in the firewall.  Why isn't windows prompting the user with
the security alert dialog?  I have the "Display notification..." check box
checked, and it still doesn't appear.  Is there something I should do before
sending the packet? 

Doesn't the security alert work with UDP packets?

Thanks
