WIndows 7

I have been using Windows 7 for 4 days and I am thinking about returning to XP.

Don't get me wrong, Windows 7 is nothing like the shambles that is Vista. In the main, it's very nice to use and does many things very slickly indeed. But that said, there are pretty basic things that it either takes too long to do, or does in an inexplicably awful way.

For example, when copying updated files to a nearly-full memory stick, it complains that there isn't enough free space on the stick. Despite the fact that all the files to be copied are going to overwrite existing files already on the stick, meaning that the required space is virtually the same. What kind of thinking is this, Microsoft?

When I copy and paste files on my desktop to a folder on my desktop, the source files are moved randomly after the copy has completed. Why?

If I want to sort a folder by date, select a few files with Ctrl-Click and then sort it by name to select a few more, the original selections are lost when changing the sort order. Again, just WHY?

Left speechless by the crass incompetence of Microsoft yet again.
