Hi - When I select a large number of files in a directory on any of our 6.5 boxes our Pcs (running 4.90sp4 or the latest 491 client) all slow down to a crawl. Explorer.exe usually runs at 99% cpu. Selecting 800 image files (all very small - no more than 60k each) takes about 3 mins for the right click dialog to display. Selecting 10 files though is nice and speedy.

Any ideas?
