This bug occurs with PsPad 5.0.7 (775) 32-bit running on Windows 10 64-bit. It has been around a long time.
Note: I manually installed the portable version of PsPad 32b into folder _C:\Program Files (x86)\PsPad Editor_, and set permissions on this folder and its contents so members of the local _Users_ group have Full Permissions. To reproduce this bug: 1. Run PsPad 32-bit and go to [b]Settings, Program Settings, System integration[/b] and make sure _Register in System context menu_ is CHECKED and that _Registry_ is selected under the checkbox. Click _OK_ to save settings. 2. Exit PsPad. 3. Run File Explorer 4. Locate a text file, right-click it, then from the shell context menu choose _PsPad_ to open the file in PsPad. 5. Make a minor edit, then save and close the file. 6. From the _File_ menu, choose _Open Special/Recent_: The file you just opened (via context menu), edited and closed is NOT in the recent files list. :-/ 7. From within PsPad, go to _File, Open_ and open the same text file. 8. Make another minor edit, then save and close. 9. From the _File_ menu, choose _Open Special/Recent_: The file you just opened, edited and closed IS now in the recent files list. So the recent files list is working, but only for files explicitly opened from PsPad's _File, Open_ menu pick. Files opened via the shell context menu are not registered in the Recent Files list. -- <https://forum.pspad.com/read.php?4,78492,78492> PSPad freeware editor https://www.pspad.com
