Two "please waits" showing up . . .

Thanks for the great module - it keeps users in my modal form windows from making dup nodes.

Problem happens not in the submit button in my modal window but with the parent form submit button. After it's clicked, two please waits show up. I think the reason this is happening is because i have other buttons on the page that are hidden via css. Those buttons trigger ahah callbacks that update the parent form after the modal form is submitted. When the buttons are not hidden they say please wait continuously after they are triggered the first time. No matter cause the buttons are hidden but they are somehow confounding Hide submit's treatment of the visible parent form submit button.

I believe i can turn Hide submit off for my parent form but i don't want to. Perhaps i can check for the occurrence of multiple please waits and remove extras via jQuery. ideas?
