I am updating a large MATLAB code from 2013b to run on 2020b. I have simplified and attached a section of it so you can just call the function to show the area of interest. The code allows you to drag and drop labels across a plotted line. It works great in 2013b but something has changed since then, and I can't figure out what is happening. I can't get it to generate errors or respond to figure out what is going on. If someone could point out the issue, that would be very helpful.

Not sure yet, but the example works in R2009b and fails in R2015b. There was a quite a bit of stuff changed in 2014. It seems like the CBF aren't running at all, but every now and then I can manage to get them to fire. Strange.

Ah. Figured it out. Set the pickableparts property of the labels.
te = text(xe,ye,['_{End}'],'rotation',45,'parent',ax,'hittest','off',...
'userdata',pe,'color',[0 .7 0],'tag','Testpoint','pickableparts','none');
