When amending a query to add a new column to the select portion of the query,using aliasname. and then further filtering e.g. typing 'A', Toad displays a blank screen instead of the columns that start with 'A'. So typing aliasname. brings up a list of columns OK. It's only when it's further filtered by letter, is when the list is empty.
WORKAROUND
Add the extra column to the end of the select list (before the 'FROM'), then it will display correctly in the dropdown
