Question about cloaking

After a redesign (Early october) to my site (www.topperswithglitz.com)
it seems to have completely dropped out of google. (There are very old
supplemental results, but that's it).

I was curious as to whether anyone knows if one of the reasons could be
the dynamic menu system that I use now. Basically there are hidden divs
with menu links that are made visible when you mouse over certain other
parts. Is it possible google is seeing this as 'deceptive'?

I've added a sitemap, and tried to make the text and content as bot
friendly as possible, msn seems to be indexing it just fine.

Anyone have any suggestions as to why I may be turning google away?

Thanks for any help...
