Open the css file: /jq_validation/Bloom.css
Add a z-index to the .Bloom-wrapper class on line 54 like this:
That should put the errors above the floating window. It looks like you may still have a positioning problem. Have you adjusted the css by hand already in that file?
I think the easiest fix will be to remove the margin-left in the .Bloom style on line 23... either that or else add the same left margin to .Bloom-before (line 61) and .Bloom-after (line 71).
