User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7) Gecko/20040514

The "products" drop down menu (used for searching) at home page of amazon.co.uk
and amazon.de often extends upwards and off the screen. The menu items that are
off screen cannot be scrolled to. Sometimes the menu will drop downwards but if
you move the browser window down a little the menu will then go up again, and
again items are inaccessible.

Reproducible: Sometimes
Steps to Reproduce:
1.visit www.amazon.co.uk or www.amazon.de
2.click "All Products" or "Alle Produkte" menu
3.if menu drops down try moving browser window down a little

Actual Results:  
menu extends upwards, making some of the items inaccessible.

Expected Results:  
displayed the whole menu

A simple workaround is to lower the browser window sufficiently to make all menu
items available.

Using Mac OS 10.3.3

Attachment: Test case

More details: Only happens when tab bar is present.
Relevant code attached. From trying out various options, it seems to me that if
the menu is >= 105 pixels from the top it goes upwards. < 105, it goes down. At
amazon.co.uk, this behaviour takes the menu off the screen.

Confirmed using Mozilla-Mac/1.7RC3. If insufficient vertical resolution exists
to display the entire menu, the menu is clipped at the top of the display.

The menu should be displayed entirely within the display boundaries.
