Global field locks when clicking onto header backg

[Rainy Pass]

A global field is formatted as a drop down list. If the user clicks in the field anywhere other than on a list choice the list collapses (as it should). However, if the user then clicks on the header area to exit the field they can not re-enter the list or execute any of the buttons in the Header. The system works fine on layouts without the Header formatting, and it works fine when clicking on the formatted Body. What is causing this? Can it be corrected other than changing the list to a menu?

Global field is:

If (

IsEmpty ( Lookup ( D_sSelectedNav::z_NavListName_t ) );TextColor ( "Select" ; RGB ( 255 ; 0 ; 0 ) );//No listName, Red

TextColor ( Lookup ( D_sSelectedNav::z_NavListName_t ) ; RGB ( 0 ; 0 ; 0 ) )//ListName,Black

)

Header is a field:

GetRepetition ( D_Setting::Color_r ; D_Setting::z_ColorChoiceHeader_gn)

Did you format Header's behavior to not allow entry?

Can you explain? The global (list) allows entry, the header color field is a calculation.

In Layout Mode, select the Header field and Format -> Field Behavior. Deselect the entry in Browse and Find mode checkboxes. If you allow entry into it, then you are still in the record when you click on it.

Thanks. So obvious once you see the light. Much appreciated.
