Thanks for this information marco,
I will download 5.1.3 version as soon as possible.
Please make this behaviour customisable. This way you won't impose "people" opinion to everybody any more.
Once again data safety can be ensured by database itself with backups, rollbacks, and with Oracle 9i you can get back datas even after delete+commit.
At this point it's nearly philosophy but "safety" net imposed to everybody because of "people" can quicly lead to hell on hearth.
Keep PlSql dev efficient it's my favorite tool.
Best regards,
