I enclose the patch I already developed for verion 0.8 (the problem is the same)
Note that this tracker is only used for SquirrelMail core and plugins that come with the default distribution, and not third party plugins. It's best to post patches and report issues such as this to the squirrelmail-plugins mailing list and to the plugin authors.
That said, I have a new version of this plugin nearing release that should alleviate this issue. As always, thanks for your many contributions.
