I have installed Version 6.2.0RC1 (Build 6311) on windows IIS6
When using Editing Leads the system always asks me to enter who the lead is assigned to.
I assign it and it seems to work fine.

If I edit the Lead again the assigned to field is blank and I have to assign it again.
The database seems to save the used id string.
In list view the entry is blank - however there is a link to the correct user.

So it seems that it does not know how to display the assigned user name.

Any help would be appreciated
