+1 although grey/disabled when no changes and Blue how it is now when changes. Is yours Black now because mine is Blue? Could be color palette/max color differences.
There has even been discussions in a few forums for other software I use about a change in Save icons in general since a lot of new comers have no idea what a Floppy is. I've been "lucky" enough to have used an 8", a 5.25", and a 3.5" in all their varieties of single sided, double sided, single density, double density, etc. I still transfer my 3.5" drive to each new PC that can support it, but can't remember the last time I actually used it. I have one 5.25" drive somewhere but have no clue if it even works.
