I hadn't considered that. Unfortunately, it doesn't seem to be making any difference. I've changed the NextPlot property to replacechildren for the axes object, and after my call to imshow(), I've reset the buttondwn callback as follows: set(handles.axes1, 'ButtonDownFcn', {@axes1_ButtonDownFcn,hObject,eventdata,handles}); but I'm still not getting the callback after the image is loaded.

Sorry to continue posting on this one, but I'm really hoping someone has dealt with a similar problem and will notice this post. I'm trying every possible combination of these properties and possible solutions, and having no luck. I'll summarize: -GUI contains an unpopulated axes object to start, I have created the following callback: function axes1_ButtonDownFcn(hObject, eventdata, handles) cp = get(handles.axes1,'CurrentPoint') guidata(hObject, handles); and it works perfectly, returning the mouse coordinates to the command window. -The axes is populated by calling imshow(). I am aware that this resets the properties of the axes object, and I have tried multiple methods of preventing/compensating for this: set(handles.axes1,'nextplot','replacechildren'); handles.currimage = imshow(handles.imagestack(:,:,1),[0 1012]); set(handles.axes1,'HitTest','on'); set(handles.axes1, 'ButtonDownFcn', @axes1_ButtonDownFcn); but the callback still ceases to function. As I mentioned, I've tried multiple combinations of HitTest and Visible properties for the axes. I have a few theories about what might be the problem: -Some property of the imshow() handle that must be set. I've tried explicitly setting the HitTest for the handles.currimage object to either on or off, but neither changed the functionality. -Some reference to a 'parent' handle, as I'm technically clicking on the image, but I want a callback from the axes object. I've played around with this, but I'm not really sure how it would be implemented. I'd really appreciate any other ideas! I've got the rest of this program finished and just need to get this final feature working.

I've got the rest of this program finished and just need to get this final feature working. a hint: - create the axis AH - set the BUTTONDOWNFCN callback - HOLD ON - create the image - set the BUTTONDOWNFCN callback of this image to simply retrieve the parent's, ie, AH, BUTTONDOWNFCN and call it as a function us
