Maybe following steps help you: 1) Close reload dialog with button No (but remember file name for next step). 2) Activate changed document (e.g. left mouse click on file tab). Would be nice if PSPad could activate this tab automatically ;-) 3) Open local menu (e.g. right mouse click on tab). 4) Run _Text Diff with file Contents on Disk_. 5) If you like changed document in disk, you can reopen it with Ctrl+R.
