Yesterday I upgraded to R2015a. CTRL-C no longer halts execution. At first I thought it might be a keyboard mapping issue- I use CAPSLOCK as a CTRL key. Switching this back did not help.
Even if I run something very simple like pause(10), neither CTRL-C (nor anything else I am aware of save force quitting MATLAB), will interrupt for those 10 seconds.
This is very problematic for me as I am working with some numerical integrals that can easily take way too much time and need to be interrupted. Of course I can change the recursion depth to deal with this temporarily but I would still like CTRL-C to work.
UDPATE: Matlab 2015 no longer correctly maps DVORAK keys for the CTRL prefix. It does map correctly for COMMAND, and for no prefixes. Thus COMMAND C still copies, but CTRL-J halts execution. I think I'll repost this with a more appropriate heading.
