Can you update to 7.1.5 and try again? This will probably fix it.

If it still fails, please modify the PL/SQL Developer shortcut and add the DebugSQL parameter. For example:

"C:\Program Files\PLSQL Developer\plsqldev.exe" DebugSQL

Reproduce the problem and send me the debug.txt file that is generated in the PL/SQL Developer directory or in the %APPDATA%\PLSQL Developer directory (e.g. C:\Documents and Settings\\Application Data).
