as the topic states, mirc does not rename an active query window from "test" to "test-n\a". It's denied with "* /queryrn: invalid window". The other way around (from "test-n\a" to "test") it works.
is this even recognized as a bug or will i have to deal with that?
Looks like a bug to me, you could work around it by creating the second query window "test-n\a" and then copying the contents of "test" into it, and closing the "test" query.
