Bulk Action, Activate & Deactive

I’m using the free version of your plugin from the WordPress repository, version 0.1.

Just wanted to let you know that if you are on the /wp-admin/plugins.php page of your WP site, and you use the checkbox next to PDF Viewer and then select either Activate or Deactivate on the pull down and then press the Apply button, it doesn’t work with your plugin. There’s a bug. Instead of working, it says “Are you sure you want to do this?”

Maybe you could try to reproduce and fix in the next version?

Thanks for all you do with this plugin!
