Difficulties with Hyper-V clients

[RichardBishop]

Thanks Patrick,

I downloaded the latest versions of the agents and this seems to have fixed the majority of my problems.

These are the steps that I took...
Downloaded new update.zip and wpupdate.zip files.
update.ini went from ver 362 -> 365
wptupdate.ini went from ver 124 -> 127

Firefox and IE are now working. :-)
The problems that I saw with Chrome seem to be related to changes in Chrome itself.

The problems with Chrome were:
...wpt driver extension was crashing.
Attempted to install it manually chrome://extensions - load etc...
...but now need Chrome beta to use unsigned extensions.
...also need to "enable Experimental Extension APIs" in chrome://flags
Despite making these changes, Chrome tests don't work at the moment. I've disabled this for the time being.
