问题
From snapshot, the grey block is the mouse over dropdown menu. What's behind it is a user input on the page.
The issue is, if the input dom is not empty, meaning user has type in something and may covered by that css menu, then there is an overlap. it is only happen on IE7.
So why and how can we resolve this issue?
