GUI error: 'Undefined function 'xxx' for input type 'struct'

Hi all, I recently started coming across the above error when running my GUI. the 'xxx' is the name of an old .m-file linked to the GUI, but I have since renamed and resaved the GUI properly and removed all occurrences of 'xxx' in any related m-files.

Since the error doesn't indicate where the reference to the old .m-file is made or at what point it poses a problem, I'm having trouble solving the issue. What is striking is that this has only started happening today, even though I've been using that same GUI daily for the past three months without any problems. The GUI still works fine, but it would be nice to stop MATLAB throwing these errors in my face everytime I click a button.

Any help would be greatly appreciated. I'm especially wondering where it could actually be referencing the old 'xxx' and where I would be able to change this manually.

Thanks.

for h = findall(0, '-regexp','Callback','xxx')
  disp(get(h, 'Tag'))
end

should display the tags of all objects that include "xxx" in the callback string.
