After converting a solution from FM 11 to FM 12 I've noticed that SOME fields formatted as drop down lists don't behave. The cursor appears in the field when clicking on it instead and it allows input right away. The value list is fine etc.
Steps to reproduce the problem
Field should respond as expected. Drop down list.
Exact text of any error message(s) that appear
In the inspector, switch the field to a pop-up and then back to drop down. Return to browse mode and all is fine.
