After hitting the return key and other....

Hitting the return key after typing in text, it hang for a moment and then re-display's the module list without filtering. Also if I trying to navigate away by clicking any other menu or the module save button while its hanging I get this error:

PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'fetch_task::admin_tools' for key 'PRIMARY': INSERT INTO {cache_update} (cid, created) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1); Array ( [:db_insert_placeholder_0] => fetch_task::admin_tools [:db_insert_placeholder_1] => 1334089630 ) in _update_create_fetch_task() (line 245 of /home/server/.drupal/7/development/drupal-7.12/demo/pressflow-7/modules/update/update.fetch.inc).
