Regression: Bueditor generated text doesn't register as typed, can't submit form

Hi,

I just upgraded from D6 to D7. Bueditor is working fine, except for an incompatibility with what appears to be a new feature in Drupal 7. The "Submit" and "Preview" buttons are disabled by default now until there is form input. But for some reason Bueditor's text that is injected into the post doesn't register as typing, meaning that users who post a comment reply that is just a smiley or just a picture or a link using Bueditor also have to manually type something to enable form submission.

Any workaround for fix for this? Thanks a lot!
