1. I cannot reproduce the issue with ESC in PrintPreview. Do you open any plug-ins at the same time thatmight cause the issue?
I found problem.
I Install program in clean directory, no plugins.
I add ESC to shortcut File-Close and in this case you perform pressing ESC in printPreview as exit from editor,
Insead return to editor.
The same problem with pressing Ctrl-F4 and Ctrl-W also.
It is not correct.
But close PrintPreview with mouse – correct. We return to editor.
