I tried it nothing hap ed on my end. It opened up.
right - what did it say?
I also experienced an "ahbrowser.exe failed" during the patches but have been able to play normally, just those crashes to desktop from those two buttons. I posted this in the latest (pre)patch thread.
<edit: follow up - clicking the full install exe cleared it up and allowed to see the arena message(s) with various live and testing updates. The help button no longer ctd either.>
<edit: and yeah the larger pop out has always been a thing for certain clipboard functions.>
