I have used InDesign since version 1.0. InDesign has always been programmed to work the way you described—to bring you back to a short time before a crash. There must be something wrong with your system.
I'd suggest restoring your InDesign preferences:
If that doesn't work, you should probably uninstall and reinstall InDesign.
Also, you shouldn't be having many crashes. That almost never happens to me.
Which version of InDesign are you using ?
Does it crashes too frequently for you?
We have three computers using the current version 2015.4. We installed the new version on Friday morning and on Friday afternoon one of the computers had crashed at least 7 times after lunch. Luckily it was being restored to current work. The other computer only crashed once in that time. (Third computer not being used that day). We are using Windows 7 Operating system so I don't know whether that would be one of the issues although it appears that there are a few people experiencing the same problem.
I'd try what I suggested above: Restore your InDesign preferences on the computer that had that problem.
Thanks Steve, I will give it a go.
