Hello. Im prety New to OM and i have started to make god simulations With the grafical Interface and now im starting to work With writhing my own Equations. My problem is that when i have writen som thing wrong like missing a semicolon ore somthing else and try to save the code OM automaticaly delets alle the code that has not been saved. These olso happens if i click on another file like another model. Then everything gets erased exept for the Things thats already saved. I now i clicked to automaticaly deletet somthing when i just instaled the program but, i wanna reverse these. Anyone know how to do these ?

Best Regards
Ruben
