Hey Method,
I found a minor bug in the screen editor.
If I delete a field from a table and that field is already in a screen, it will still show in the screen editor. It will cause an error when loading the screed, understandiably.
Here's the problem.. If I go into the screen editor, I can not delete the field box (of the deleted field) from the screen. If I try to, method freezes and the browser kills the process.
The only way to delete the field box is to re-add the field to the field list, delete the field box, then re-delete the field from the table.
