It seems to be impossible to enter the enum column declaration properly through the “New table” screen that pops up when you right-click on the database name and select “Create Table.” There is no place to enter the enum values.
This seems to be the case with version 5.02 as well as earlier versions.
P.S. Never mind, somebody already mentioned it…
