[SOLVED] how to style child page links in menu?

Can anyone tell me what the specific selectors are for the drop-down child pages in the pages menu?

I'm using WP 3.0.3 and ATA 3.5.3 with all bugfixes installed, but I just can't for the life of me, find the selector that allows me to style the drop down pages in the menu, and not the parent items in #menu1.

I've used JD's menu cheat sheet and all works, but I've inspected the element in chrome's debug mode which says its ul.rMenu-ver and under li.page-item page-item 40.

Short of styling every single sub-page item, I'm really stuck with this. I'm probably missing something really obvious but I've been playing around with this for a couple of days and all objectivity and patience has now gone and I need help!

All I want to do is to get rid of the background-image for the sub-pages and replace it with a block colour (and play around with the padding a bit). If anyone's had this same issue and came across the solution, I'd be very grateful if you could give me some pointers.

Thanks,
Angela
