Hey, I have been experiencing nicklist glitches with 7.36.
After debugging a bit, I've found that I had a line like this in my mirc.ini file under the [fonts] section:
with no fontname after the '=' sign. I am not sure how this actually happened, I didn't touch the ini file myself, I never used the popups way to change the font but I often use "/font fontsize fontname" manually on an active window.
I tried to get mIRC to update mirc.ini with such a line using /font but couldn't reproduce it.
This line is the cause of a major bug with mIRC, the nicklist's content of a channel is incorrect, it's filled with the data from a different network/channel and/or with invisible (but supposedly correct) nicks: video bug nicklist
Notice how the nicklist appears empty, though there are lines in the listbox
I also tested with this line on 7.35, same result
