HERE using the /window -gN command for a @window, it now flashes the windowbox icon instead of JUST hiliting the windowbox name. In my case I use a custom /whois script that displays it to the window called @whois and the ONLY thing I use outside of the text manipulation is
/window -g1 @Whois. This didnt happen at all since I scripted it (at least a version or two ago) so it's somethign new.
