Folder Icon Options

I have set up folders which contain programs. For example I have a folder called MS Office and within it there are icons for Word,Excel and Powerpoint.

The size of the icons was set at medium and had been working fine.

3 days ago, something changed and now the icons show about with the details option set.

I have gone back and changed them numerous times from details to medium icons and it works for maybe a couple of hours and then they are all changed back to details.

How do I fix the issue so the icons always display as medium size?

Thanks
