WindowButtonDownFcn tries to access a callback function that no longer exists

I have been working with the WindowButtonDownFcn. At one point, I implemented
set(myfig_h,'WindowButtonDownFcn',@seeFit)
where seeFit is my callback function. Later, I deleted this line of code, and moved the seeFit function to a different folder because it was not needed. Now, whenever I try to run my code, I get the error
Undefined function 'seeFit' for input arguments of type 'matlab.ui.Figure'.
Error while evaluating Figure WindowButtonDownFcn
How do I prevent this from happening? Thank you very much!

Apparently the line of code is still there. Either it is saved in a .fig file, or you didn't actually delete/comment the line.
You can prevent this by explicitly assigning another function to it (or an empty one).

And explicitly setting the WindowButtonDownFcn doesn't solve this? If that is the case, try restarting Matlab (and maybe even your OS). If the problem persists, I think this would rise to the level of a bug that you should contact Mathworks with, unless I'm missing something.

I found the seeFit reference; it was buried in a function that was being called. Thanks for your help!
