Drush auto aborting, can't update modules

Hello

first thank you for this module. It's fantastic, it helps a lot.

I can't get to update my modules on a multi site install.

Modules are in the sites/all/modules/ dir

I perform an update command :

drush --uri=http://www.mydomain.com update

Here is the output :

NOTE: A code update for the Drupal core is available.
Drupal itself can't yet be updated by this tool. Please update Drupal manually.

Code updates will be made to the following projects:
Token [token-6.x-1.12], Webform [webform-6.x-2.7], Wysiwyg [wysiwyg-6.x-2.0]

Note: Updated modules can potentially break your site. It's not recommended to update production sites without prior testing.
Note: A backup of your package will be stored to backups directory if it is not managed by a supported version control system.
Note: If you have made any modifications to any file that belongs to one of these projects, you will have to migrate those modifications after updating.
Do you really want to continue? (y/n): drush: Aborting.
Drush command could not be completed. ^[[31m^[[1m[error]^[[0m

Drush auto aborts and I can't have my modules updated.

Thank you,
Serge
