For some weird reason, OrCAD Capture complains that the design file is opened read only, even when it is not.
If I right-click the .dsn file in explorer, and click properties, the read-only checkbox is not checked. I can rename, copy and delete the file no problem (I have a backup). If I delete the opj file, and open the .dsn, at first, things are fine - I can edit and save. I then close the application, and the .opj file appears. When I open the .opj file, OrCAD capture complains that the file is read only. What the heck is going on?
Is there some obscure option I have selected by mistake? Has anyone had this happen before?
Any help appreciated.
