I haven't encounted this as an issue at all. And I've been in and out of the editor alot in the past days since it came back online. And on at least 2 different machines with different hardware to boot.
I assume you know the drill though, force verify, check your drivers, check video settings to see if something there, yada yada
Just logged on the Foundry since that problem occured and it's working normal. So it's a safe bet the CTD was directly linked to the Patcher / Launcher problem that was occuring at the same time.
My suggestion to the Foundry team, to add somekind of security / notification measure that indicates that such problems is due to server issues and not a real error (which people will assume if they see that Error Box pop up and then STO closes to desktop). Also be nice if it defaults to the login or character screens when that happens (if possible).
NO to ARC!
