CompositePack drawer overlap plone 2.5

I’m experiencing a problem where the Kupu drawer used to select content when in design mode on a compositepack page gets overlapped by elements from the underlying page. I thought it was something I had done with a custom skin I was building, but when I switch back to plone default skin, the problem still exists. I don’t think I have come across this before, so my conclusion at the moment is that this is something unique to Plone 2.5

I am seeing this on Firefox 1.5.0.6 (PC & mac) and IE6 PC. CompositePack 1.0 Final

If anyone has a fix for this please let me know!

UPDATE: Fixed

I have now fixed this (thanks Emyr!).

I applied the following to my style sheet:-

.kupu-drawer {
z-index: 3 !important;
}

#region-content .contentActions {
z-index: 1;
}

(the !important is only necessary because of a precedence thing somewhere along the line)
