I have show mode prefix disabled, but when an op leaves the channel, it still shows the mode prefix for that op. It seems to occur with the @ prefix. It occurs for both quits and parts.
well im not sure if khaled meant for it to be on all the time even if its disabled in options but in the new versions.txt
28.Nicknames in channel part/quit messages now show mode prefix.
so i dont know if this is a bug or an intentional doing ... as it doesnt say if its able to be disabled? would be nice to have khaled answer this one himself to see if it is a bug or not.
also i just tested on mine in a clean install of mirc ... and it does disable the mode prefix when u untick the show mode prefix box... so id have to assume yours is either a random fluke type bug or a script interferring.
