I think I may have found a bug in the options. If you enable a firewall/proxy in Options->Connect->Firewall By choosing Server or DCC in the dropdown menu, the option None disappears (which was previously selected) and is replaced with Both. I couldn't find a way to disable the firewall without editing mirc.ini and manually turning it off.
I have 2 computers 1 has WinXP, it does not have this problem 1 has Win98se, it does have this problem maybe useful information, maybe not, thought someone may like to know
It is OS specific, Specific to every OS except XP.
I just switched from Win2K pro which did have the problem, to XP, which doesn't. So it is not just Win98 that is affected. Rather, It is just Win XP that isn't.
I didnt say that win98 was the only OS effected, nor did i intend to imply that. My only intent was to thank the poster and tell him we were already aware that it is dependant on the OS being used.
