Potential issue with SD5 with service pack 10

We have just updated our ServiceDesk implementation from 5.04 to 5.10 and we have noticed a few problems which I just wanted to share with people. Firstly, we had scanned a number of new workstations just prior to the upgrade and these have now gone missing. In addition, when logging a new request, there appears to be a new feature which allows you to select a requester from a list which appears when you type the first few letters of a requester name. If you select the user from this list, their workstation ID will not be displayed when you save the request and nor does it appear in the list of requests against that workstation. In the circumstances, I now have to tell everyone in the Helpdesk team not to select requesters using this 'enhanced feature' which is a right royal pain. If anyone from AdventNet is currently on this forum perhaps they could let me know how and when this might be fixed. Many thanks.
