package compile issue

Hello
When I compile packages which have error the toad get freezing, and the packages which haven’t errors they compiled successfully.

The strange thing when compile the same package on sqlplus it runs successfully without get freezing.
Note:
There is no database lock happened during package compile.

Oracle database version is: 11.1.0.6

Toad version: 11.6
bye

I haven’t get any reply so far…
