good grief!....what a mess since I last was here!

one thing that EVEN geeks should know...you COPY files, not move them...then you triple check to be sure they are where you want them..THEN you delete.(yeah, yeah....now he mentions it!)

My PC now & then seems to hiccup and delete/rewrite all the icons, as if it were a temporary memory cleaning..it is a slight nuisance, but it never harmed any.

Sorcha...in the original post you said your icons were 'only half there'....did that mean fuzzy, or just 'top' half...or something else?

can you right click on an icon and get a list with 'properties' at the bottom? On my machine, this allows you to click 'properties', which gets a screen with 'change icon' as one option...if it gives you an easy choice of other icons, it might be a useful test to see if changing one helps. (I have all sorts of 'different' icons, and mess with them regularly, just to please myself).....

I ask this because all sorts of trys are better than just reinstalling Windows as a 'catch-all' fix. As you see, too many things can go wrong, go wrong, go wrong, go wrong, go wrong,go wrong,.............
