Using HTML Area & Workflow causes page to freeze when editing in FF 1.5.0.11

I am using Drupal 5.1 and htmlarea 5.x-2.0. I am also using workflow 5.x-1.1. I have given pages workflow and have given the administrator permission to basically do anything with a page in any workflow state. There are two states - draft and done. A page automatically goes from creation to draft when it's created, but isn't published automatically. When I go in as the administrator (or a site maintainer, which has a few less permissions) and try to edit one of these nodes (which is in "draft" and "unpublished" status) in Firefox 1.5.0.11, I can see the content of the page load briefly in the HTML Area window, then it disappears, the screen freezes, and I have to re-start Firefox. I can edit a "published" page with a status of "done" just fine in FF. However, I can edit neither an "unpubished" page with a status of "draft" nor a "published" page with the status of "draft." The action that occurs when the status is changed from "draft" to "done" is that the page is published. After a page is created, it is automatically placed in "draft" status and an email is sent to the admin (I basically followed the example in the Workflow README.txt document). I have none of these problems in Internet Explorer 7.0, and have none of these problems when I don't use workflow or turn off htmlarea, so this appears to be a bug with htmlarea & FF when workflow is used.
