[Typo3] Only admin-User can edit fields in extension

[Tom Walter]

I am using xinittwocolumn-extension. All the time I only used an 
admin-User in the BE to create and edit content. Now I wanted to set up 
a user and a group (which actually for the normal content works fine).
The normal can only edit one field from the extension.

Can anybody help out with some ideas ?

I got a feeling, that this part of the ext_tables.php is the source of 
the problem. (however I am not sure and open to any suggestions ...)

Thanks a lot !
Tom
