I found this bug happening from time to time in the current as in earlier versions of mirc.
this is - or should be - in the performlist:
it's there because "mynick123" is the alternative to "mynick" if this one is in use. the numbers at the end are important. now this works for some time, but then suddenly mirc changes the order in the list to
and it cannot be reset to the correct order, no matter what I try. I even tried to write-protect the performlist-file, but mirc doesn't care about it.
I don't know why or by what circumstances mirc does this, it just happens. and it's getting on my nerves, because there is this "Nick change too fast." from the server, forcing you to wait before you can change back to the desired nick...
Anyone with an idea or a workaround for this? Or is it a known bug not corrected for some reason
