Json error after upgrade 5.1

[Systems Navigator]

Hello,

I experience an error after I upgraded my sugar instance to version 5.1.
If I am in the products module and I edit a new record I was able to select a product from the catalog. However when I try to select a product now I get a popup in my browser which says:

ERROR CONNECTING to: ./index.php?entryPoint=json_server, ERROR:ReferenceError: JSON is not defined.

The problem occurs after I click on the select button and select a product from the catalog in the pop-up screen.

This error I get using mozilla firefox. When I use IE7.0 I get the same error a little bit different formulated.

Does anybody know what this could be? All other relate fields in the module are working properly.

Thanks in advance,

OS: Windows 2003 Server R2
Sugar: Version 5.1.0 Pro
Webserver: apache 2.0.59
PHP: Version 5.2.5
Mysql: version 5.0.45

We have same issue with Sugar Proffessional Version 5.1.0a (Build 4837)... screenshot here:

In my case it solved the problem by deleting the custom folder of products and recreate the layout in studio. I think with the migration to the new version some bugs infiltrated with the custom fields.

Hope this helps.
