Is this expected behaviour? I couldn’t find any reference to unsaved changes behaviour in OG 7.
I was working on a file, saved what I was happy with, then experimented with a bunch of crap in the same file. I closed the file to discard the crap and work on something else. To my dismay, there was no “you have unsaved changes” dialog, but the unsaved changes were silently saved! Worse, next time I opened the file, the undo history was gone so I had no way to return to my deliberately saved version.
Is this supposed to happen? How do I avoid losing my work next time? Should I be noting the clock time whenever I deliberately save, in case I need to restore from time machine? Or should I be selecting “revert to last saved” before closing a file? Both seem pretty preposterous, so I feel I’m missing something.
