Please see connect ID 772739 - I have added more details. I have talked to microsoft support as advised and they have told me to come back to Studio support (case 1189236108). I am not keen on getting bounced around support - is there someone technical that can take a look at this please?
This could be a Win 8 problem but support says it is the development tools...please escalate so it is looked at by someone technical! I have tried to tell them myself - can someone champion this for me within Microsft please?
