We are about to switch to a new forum software. Until then we have removed the registration on this forum.
just I loosed my work of the day by the following mistake: suddenly a message appears: "your sketch has been modified externally" with Yes/No buttons, but the No button returns the same message and if I push the yes button Code of the last session is deleted e.g. in my case a whole class. Is there a solution of this problem?
Help is appreciated. Thanks.
