OpenOffice stuck on restore window at each start

Recently, my OpenOffice was always prompting for a ‘restore file’ window, but the file was not on my system. The restore failed all the time and I couldn’t find a way to avoid that popup.

Here is the solution:

Close OpenOffice.

Open the finder, and in the top menu ‘Go’ hold the Option key (ALT), the Library folder should appear. Open it and navigate to: ‘Saved Application State’ and delete the folder called ‘org.openoffice.script.savedState’

Run OpenOffice, the popup should have disappear.
