Create a new one, switch to it and drop the old one.

I do not have the same behaviour that you.
Use SQL*Plus and copy and paste your session.

Before, please read OraFAQ Forum Guide, especially "How to format your post?" section.
Make sure that lines of code do not exceed 80 characters when you format.
Indent the code (See SQL Formatter), use code tags and align the columns in result.
Use the "Preview Message" button to verify.
Also always post your Oracle version (4 decimals).

Regards
Michel
