You are not going to be able to solve these issues with css alone. As you already know, IE doesn't support the :hover pseudo-selector, so you will need to render your links inactive by adding href="javascript:void(0);" to your links. I highly recommend craigsworks.com/projects/qtip/ as a jquery solution.
You can specifically set hover conditions and the funcitonality degrades with js off and it even works with IE6. Also, you can apply these tooltips to any tag, solving your anchor issues. Even with this plugin, you still have a problem with tooltips overlapping list content, so you should position them to the side of the list.
That way you can hover your mouse straight down the list with no interference from the tooltip.
The answer to the crashing is that IE simply crashes in many edge cases on hover, especially if certain key elements don't acquire HasLayout. Baloneysammitch's idea of putting the popups to the right is also good.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
