I also want to report that I received the same type of message a couple of time while using AFNI interactively. I did not do anything extraordinary, for example, once AFNI shut down when I was adjusting the color bar. The message I received is
Fatal Signal 11 (SIGSEGV) received
MCW_textwin_alter
AFNI_set_viewpoint
AFNI_seq_send_CB
ISQ_drawing_EV
AFNI:main
Bottom of Debug Stack
*** Program Abort ***
Would be great to fix it somehow.
Thanks
Kristina
