Last night I was trying out a different program for writing. Usually I use Screenwriter, which I bought for myself because it had templates for a lot of different formats. This time, I decided I would try this different program which was supposedly geared more towards novel writers. It seemed okay, and got some decent reviews.
The one thing I did not check was to see if it had an automatic back-up, which Screenwriter, and most such products do. If it did, it was not set up to run. So, when the program glitched after a half an hour of writing last night, I discovered that none of it was saved.
I switched back to Screenwriter minutes afterward.
