Hi. I love this menu. It works beautifully and was easy to customize. However, I'm getting an issue with page loads. On initial load, my content is pushed to the bottom of the screen, and then pops into place after a fraction of a second (on high speed access, takes a few seconds on low bandwidth to pop into place). Is this an issue with the code <ul id="menu" style="visibility: hidden">? It appears the amount of space my body content is pushed down equals the space the menu occupies when I view the page in "Design" mode in Dreamweaver.

How can I fix this page load issue?

Much respect and appreciation in advance for your help,
--Robin.
