1 make a morph head,
2 add morph eyes, and morph mouth.
3 go back and update / switch / edit the head graphic with sprite editor - load new graphic.
4 click the eye and mouth feature to readjust to updated image, ( the quick access eye and mouth icons )
it will leave the software hanging. This is because when you replace the head image, it removes the morph mouth and eyes - but the quick edit features still attempts to edit the parts that are no longer there. you have to taskbar - force close the software to escape it.
this happened because i wanted to tweak the head graphic but there is no send to photoeditor option for the head - so I just replaced the graphic and discovered this glitch in the process.
