Yes, as far as performance goes, explorer sorting is the only thing that is slow. Windows Media Player is rubbish on my system as well.. general instability and such. Everything else is fine.
I use list mode, but it happens in any mode.. thumbnails load quick and snappy
Sorting by name and opening a folder for the first time bogs like I mentioned. I can go into a folder, and out again and it's fine.
But if I sort by DATE, it bogs while sorting... I go into a folder, and out again and it bogs as it sorts again.
The folder in particular that I test this on has 90ish folders and 200 individual files.
XP never had this issue with the same amount of files... The drive is also entirely defragged. If this isn't a widespread problem, then I am stumped.
