thanks a lot for your prompt reply, and I changed my vote to work 🙂
Hi Tubal,
I am using wordpress 3.2.1
After my first install of the plugin, the WYSIWYG editor disappeared, and it appears again after I deactivated it.
Another plugin that add button to the editor is WP-Table Reloaded, I am not sure if it has any effect on your plugin or not…
However, its fine now after un-install and re-install your plugin again. The problem seems caused by not refreshing the cache of the WYSIWYG editor after my first install of the plugin.
