I've been using the previous version of WinUAE for some time and was always a little curious about why my floppy disk files were stuck on 'read only'. But it didn't bother me because I'd just copy files I wanted to change to my hard disk file.
Until my hard disk file also became 'read only'. I know there's a little dialouge box to change such things for hard disk files but it's just not doing the trick. I downloaded the latest WinUAE and started with a new hard disk file so I guess I'll get around to mounting my old one and copying files over - has anyone had a similar experience?
