There are apparently at least three hidden columns on the right side of the SQL results pane. They can be selected by dragging the cursor (it turns to an arrow when it's at the left side of the cell) all the way past the displayed columns. They're obviously used by PL/SQL Developer to track statuses, updateability, etc. For example, after executing "SELECT 1, 2 FROM dual;", these columns are "XX", NULL, "U".
This isn't a big deal and I don't care if it's fixed or not. It's just something I came across and thought it was interesting.
