There have been many times that I have been editing an equation and I end up clicking something outside of the equation editing box for some random reason and then all of my changes have been lost! Ugh! So I have been trying to remember to hit enter more frequently during editing so that I can save incremental changes just in case my editing happens to get interrupted for what ever reason, but I just really wish that everything would not disappear like POOOF with no way to recover my changes.
I look into it and see what can be done.
Thanks a lot,
