'Assigned to' field is gone on Leads Edit View

[kmideas]

I'm new to Sugar and think I messed something up when I was in the Studio.

On the Leads Editview layout, 'Assigned to' appears on the Toolbox, however when I drag it to the Layout Preview and Save, it bounces back to the Toolbox.

Then I noticed the 'Assigned to' field is not on the Leads list, however the label is on the Lead list of labels.

How do I fixe this?

This is running on Windows XP,
CE 5.0.0g
IIS 5.1
PHP 5.2.2.6
MSSQL 2005

Thanks for your help

Never mind.. I upgraded to 5.1a and that solved the issue.
