Guild Wars 2

I’ve been running fine with GW2 since the patch. I use Avast!, so one of the first things I had to deal with was letting CoherentUI_Host.exe do the things it wanted to. No problem.

However – out of the blue today, I went to try to use the BLTC and Avast! popped a pair of new requests for permission for CoherentUI_Host.exe. I frowned a bit, then agreed. At which point my game went into lag overdrive, with the client graphics stuttering and the whole thing generally unusable. Bringing up task manager (I’m on Win 7), I could see two copies of the process running at 25% of CPU each, plus GW2 itself (also at 25%). I closed GW2 down – the client went away, but none of the processes, and the CPU figures stayed static at 25% for each. At that point I restarted Windows, opened task manager, then started the GW2 client. I could see that there were, again, two copies of the CoherentUI_Host.exe process (I realise that that may be the normal state of affairs – I wonder whether a previous one crashed silently, and a new one was started?).
