access to handles structure in WindowButtonDownFcn

Hello,
I've got a GUI, and I would like to be able to access the most up to date handles structure in the WindowScrollWheelFcn and WindowButtonDownFcn. Currently I can only access the handles structure as it has been set in my opening function.
At the moment I have the following opening function:
function openFile_ClickedCallback(hObject, eventdata, handles)
(other stuff happens here)
guidata(hObject, handles);
I then do some some other routines which change some of the variables stored in the handles structure (all functions with guidata(hObject, handles); at the end of them) and then have the following function which occurs on a mouse click:
function figure1_WindowButtonDownFcn(hObject, eventdata, handles)
(other stuff happens here)
handles.startingPoint = get(hObject, 'CurrentPoint');
set(hObject,'WindowButtonMotionFcn',{@wbm, handles});
set(hObject,'WindowButtonUpFcn',{@wbu});
guidata(hObject, handles);
Am I missing something obvious to be able to access my most up to date handles structure in the above function? It seems to happen only with button related functions such as WindowButtonDownFcn and WindowScrollWheelFcn
Any ideas?
Thanks
Jim

You can update the handles dynamically:
handles = guidata(hObject)
or
handles = guidata(handles.hFigure)
if hFigure contains the handle of the figure.

Hi Jan,
I'm already updating dynamically at the end of every function to make sure I have the most up to date handles.
It seems to be just the mouse button click where my updated handles structure isn't appearing
