If [x]Save file state (Program settings / Files) is enabled, PSPad remembers R/O of each file. R/O state of file in the PSPad should be different from file aatribute. You can set R/O to file you don't want to accidentally rewrite, but file has no R/O attribute and you can rewrite file in the PSPad even has a R/O attribute. Use a tool button with the "lock" symbol or menu File / Read only or file tab context menu
