I have over the last few days logged a bit of time online in AH and enjoyed some hectic scraps when you need your head on a swivel.
It did confirm that it is not a hardware issue. My view hat switches were not stuck. I had the presence of mind on a couple of occassions when the view stuck to leave the stick alone and check the stuck view with the numbers pad on my keyboard. cycling the view on the keyboard cleared the problem so the view was definately not stuck on the hatswitch.
As for a solution, well I had upped my character rate in the CH Program manager to 60 (used to be 25). That made no difference, so I have now set it to 100. I'll post back when I have had a few more sessions
