A bit of a strange problem has cropped up on my PC.
I run XP Pro on
Intel Duo 2 Core e6600
Lots of disks and a Synology DS107e on a LAN
When I open a drive with explorer by double clicking I get the normal single pane window, but if I try to go down more than I level the window freezes and I have to termibate explorer. The toolbars and desktop icons disappear and then come back. If, however I open the third level by right-clicking and selecting "explore" it opens the 2-pane window and works fine!
Has anyone seen this before, or have any bright ideas how to fix it?
