TinyMCE filtered buttons only on plugin page

Hello,

I am half way through writing my plugin. Basically that plugin has option page and it has content area to user to write something. I am using TinyMCE by calling wp_tiny_mce.

Moreover, I used tiny_mce_before_init filter to remove un-necessary buttons from the editor. The problem is when I used tiny_mce_before_init filter, it will effect all the TinyMCE editors on the blog which includ editors from post edit and page edit.

So how do I run that tiny_mce_before_init filter only on the plugin option page?

Could you please help?

Thanks in advance!
Tristan
