Not updating a CLOB field?

[M Myers]

I'm using PL/SQL developer version 6.0.1.848 against an Oracle database version 10.2.0.3.0. There is a CLOB field that I'm trying to update but it just won't take. Here are my steps:
1) I've selected the record 'for update'
2) Then I select the 'Edit Data' icon
3) Press the elipse button to bring up the large data editor
4) Then I delete some of the text I don't want (still leave most of it)
5) Press the OK button
Here is my first clue nothing happened because the 'Post changes' checkbox isn't highlighted.
6) Now I execute the 'commit'
7) Query everything back up and nothing has changed.
Is there a bug with the version of PL/SQL developer I'm on against the database version? We previously had Oracle database version 9.2.0.5 and I had no problems with the steps above.
Any advice would be greatly appreciated.
Thanks

Can you update to 6.0.6 and try again? This should be fixed.

My company upgraded me to 7.1.4 and it now works. Thanks for you help.
