PROBLEM STATEMENT:
I assume there is only one "focused" state for the accessibles, but

REPRODUCE:
1. run uia2atk/test/samples/menustrip.py
2. run accerciser
3. browser to and select "File" menu from left pane of Accerciser
4. open "Interface viewer" tab, and click "Accessible" 
5. press "alt+F" shortcut key to access "File" menu
6. there are "selected" and "focused" states added for "File" menu in "States" textbox 
7. browser to and select "New" menu item under "File" menu from left pane of Accerciser
6. press "alt+F" shortcut key to access "File" menu

RESULTS:
there are "selected" and "focused" states added for "New" menu item in "States" textbox 

for "File" menu:  +focsed, +selected
for "New" menu item: +focused, +selected, -focusable

EXPECTED RESULTS:
I guess "File" menu shouldn't has "focused" state, but "New" menu item?

for "File" menu: +selected
for "New" menu item: +focused, +selected, =focusable (= means not change)

but the expected results that I'm not sure, 

COMMENT:
Note that the "focusable" state of "New" menu item disappeared when you use "Alt+F" to access "File" menu, and "focused" state added for the "New" menu item.
