Z-Index issue when deleting a question

Hi guys,

I'm using the latest version of Community Surveys and Joomla 2.5.9 with Rockettheme Graffito.

Just to report that when I try delete a question from the front-end I am getting a z-index issue where the grey overlay is infront of the confirmation message to delete the question. So I simply hide the overlay and they confirm the deletion.

Just thought you should know about this for the next release.

Cheers.
