Login/Register tabs don't stay open in CHROME

My website is www.ivychuang.com.

I have not made any changes to the login/register functions.
In a Chrome browser, when I click on Login or Register, the drop down appears,
but when I click on a input box, the drop down automatically closes, making it impossible to input any information. When I click-and-drag inside the input box, then the cursor appears and I can input.

How do I fix this bug?

In Firefox and IE, this problem does not occur.

i get same error in latest chrome also on demo page., i report this to the programmers

this is already fixed i see... please update to latest version...
