Thanks for the suggestions. I have tried several different techniques with no luck, but I have noticed something else now. If, after touching "bookshelf" I quickly touch just below it, I click a link! So, the drop down menu IS dropping down, it is just completely invisible. I did this blind clicking maybe 35 times and finally got into my shopping list-ha!
So, I don't know if this is an issue with compatibility, or just my browser (if it is, I am lost--I am hopeless at this stuff) but I would be curious to know if anyone else is having a similar problem.
I wonder if EYB plans to include a link to the shopping list anywhere else on the site? Or if there is one I don't know about? Most of the other options on the Bookshelf drop down can actually be accessed in other places (magazines, blogs, etc are all available on that horizontal tool bar) but this drop down seems to be the only way to get to the shopping list!
