sophos admins - how are you finding the new version?

Just wanted to know if any of you guys who use sophos on your networks are having any problems with the new enterprise client, the new av client (v5) and deploying it onto workstations that have the old client on them (v3.x).

I seem to have a strange issue where it fails to deploy the av software (tho the remote manage and autoupdate componants sucessfully deploy) due to "failure to uninstall previous version"... however, quite often over night the software will sucessfully deploy automatically!

I have sophos tech support really confused and myself annoyed! It'll work when manually installing from the CID but only if the previous version has been removed first.

Any other sophos users have this problem with the new enterprise manager? Tho I think it is an immense improvement over the old savadmin app - policies instead of config files makes life soooo much easier on machines that have the new client running
