Sometimes it seems that popup/Drop Down Lists do not appear to show focus in 4Dv6.5. Turns out that is not true, EXCEPT under a particular circumstance.
If you had a Drop-Down List in 4Dv6, and converted it to 4Dv6.5, these objects will be converted to Popup/Drop Down Lists, BUT they will have an ACTION set to No Action. You need to go into the design environment and CLICK this popup set as No Action. It will then disappear altogether, because a Popup/Drop Down List has no choice under the ACTION category. Once this is done, the Popup/Drop Down Lists behave normally.
