I have one (of several) reports in my front end which opens in Report View. The report can be placed into Print Preview, either by clicking the Windows print preview icon or clicking the Access tab and selecting print preview. When exiting Print Preview, I am in the habit of doing so by hitting the Esc key on the keyboard. This causes Access to stop working and close. It does not create a backup file. it does leave the lock file open, but you can open the front end again without any problem. Exiting by clicking the red X Close Print Preview button on the ribbon, or just "X"-ing the tab closed does so without this problem. The record source is a simple 1 table query.
None of the other reports exhibit this problem.
I have not found this problem in internet searching, though I have not yet tried the Microsoft Community.
I would appreciate hearing from anyone who has experienced this or may have some causal theories and solutions.
Thanks
