I need help with this plugin.
http://wordpress.org/extend/plugins/events-calendar/

I am using for my site, and need to figure it out something.
When user mouseover the event, pop-up comes up that shows the description for the event, however the description is transacted.

I need to show whole description for each event when mouse over screen comes up.

I am not sure if this is done in CSS, php or js files included in the plugin.

Any suggestions appreciated.

thanks
