Why does the right-click context menu appear at the bottom of my figure instead of at the mouse pointer location when zoom is enabled in MATLAB 7.0.1 (R14SP1)?

I created a GUI in GUIDE containing a pushbutton that toggles the zoom of the axes in the figure. When the zoom is enabled and I right-click on the axes, the context menu appears at the bottom of the figure instead of at the location of the mouse pointer.

The following is my callback function for the zoom pushbutton:

function zoom_callback(hObject, eventdata, handles)

% This button toggles the zoom of the axes in the figure.

This bug has been fixed in MATLAB 7.0.4 (R14SP2). For previous releases, please read below for possible workarounds:

We have verified that there is a bug in MATLAB 7.0.1 (R14SP1) in the way that context menus are displayed in some GUIs when right-clicking on the axes with zoom is enabled.

To work around this issue make the following changes to zoom.m:

1. Open zoom.m by typing the following at the command line:

edit zoom

2. Rename zoom.m to zoom_old.m in case there is a problem and you need to revert to the original version.

3. Make the following modification to zoom.m around line 327

After the call to

hui = localGetContextMenu(hZoom);

Replace the following three lines:

set(hui,... 

       'Position',get(hFigure,'CurrentPoint'),...

       'Visible','on')

with the following four lines:

curr_point = get(hFigure,'CurrentPoint'); 

curr_pixel = hgconvertunits(hFigure,[curr_point 0 0],... 

get(hFigure,'Units'),'pixels',hFigure); 

set(hui,'Position',curr_pixel(1:2),'Visible','on')

4. Restart MATLAB

5. Execute the following command at the MATLAB command prompt:
