Dragon losts proxy server settings after switching to "Use direct connection"

Don’t know it’s a bug or so…
But everytime I switch from the “Use this proxy server xxxx xxx” option to the “Use direct connection” option, the proxy settings are lost and I have to refill the blanks again

system: win7 ultimate sp1 x32 chs
default theme
