Well, it's still happening, but less frequently. I just lost 2.5 hours of painstaking work b/c Sigil hung then insisted on closing when I was trying to place a picture. I am not used to having to manually save every 2 minutes so I don't lose my work. I'm used to Word that has an auto-save feature every few minutes. Does Sigil have any such feature?
EDIT: Please tell me there is a temp folder somewhere where I can manually pull my file from ... I am not opening Sigil again b/c I don't want to overwrite any possibility I could retrieve the file as it was when the program crashed.
EDIT#2: I found the temp folder dated today but the HTML inside is from before I started working. This is enough to make me use another program.
I will first see about designing a macro to auto-save every 5 min. I just can't remember to autosave constantly when I'm busy working. This seems like a trivial feature to add to Sigil, but I'm no programmer.
