Corrupting notes

An occasional problem users encounter is finding that the Notes they have
saved onto a computer are corrupted when they try to read them back. This
is almost invariably caused by trying to open, read, print or otherwise tamper
with the Note while it is on the computer. If you view the file once it has been
stored by double clicking on it to try to open it then the computer may try to
edit it with one of the word processors you have installed. If you allow this

unintentionally opened a file in this way then exit from the word processor
without saving.
