Under Vista RC1, /server -n responds with the error message "ssl not available" even though the SSL dlls are available for mIRC to use. $sslready is also false.

/server -m, however, works fine. Also strangely after the first /server -m, /server -n works normally. SSL still doesn't work when it should, though.

On a related note, the HLP format is not supported under Vista. mIRC's help will need to be converted into CHM (I find it worth noting XP's winhlp32.exe runs just FINE under Vista).
