Try this pasted to the header custom markup.

<style type="text/css">
#scs_navbar{
position: absolute;
z-index: 1000;
}
</style>

Make sure you remove the other. I also looked at your code and found some that may be affecting what I posted as there's a stray z-index reference that looks like you may have placed there but I'm not totally sure.

Hi Eric:

I think I fixed my issue, and I agree that the menus themselves should be coded so that they have a high enough z-index so they are always on top.

I suggested it to CC but I got the usual black hole answer "I'll pass that on to the design team" or something like that.

I had this same issue before with another one of the themes I was using, so I imagine it's a problem across the board with all of the CC themes and menus.

Let me know if you see anything else or if it's not working.

I see you changed it to relative positioning.
<style type="text/css">
#cc_webcalendar{ position: relative; z-index: -1; height: 740px; width: 700px; }
</style>
