automatically re-opening documents after restart? Come and gone!

[babette]

I have been using TextPad for many years and i'ts like my second brain - but I'm not very computer literate.
It has always been a problem that after a restart the files that were open did not automatically reopen.
Recently, all of a sudden, they all re-opened after restart! This was a true hallelujah moment!!!
BUT - it only did that for a few restarts of my computer and then stopped again inexplicably. So, back to the drudge of re-opening everything manually.
Could anyone help me and explain what happened and how I can restore this wonderful possibility??

(I have version 8.8.1)

Have you checked the option to automatically save every few minutes on Configure/Preferences/Backup?
