Scheduler does not allow drop down Top Menu to overlay

Discontinued products Scheduler for Joomla and WP
#1

I am using Joomla 2.5.9 and have created a Top Menu with drop down options.
This works fine on every page except the DHTMLX Schduler.
The drop down menu does not overlay the scheduler.
Is there a setting that needs to be set to allow the drop down top menu to overlay the scheduler?
I do not think that it is the template because this is ok every where else.
Thanks in advance.

OK - I figured it out.
I just set the z-index in the css for the meny to be a higher number than the DHTMLX scheduler.
