Windows Explorer takes up full CPU at times

When I have a certain location open, Windows Explorer takes up nearly all
of my CPU usage. My Sidebar Gadget (Multi Meter) is showing full usage
to ~95 for both cores. I open up the Task Manager, and the
"explorer.exe" process is using up my whole CPU. If I close the
offending location, it drops down to normal (~5%). One of these places
is my removable HD, E:. The green loading bar finishes progressing and
thumbnails/icons all load, yet explorer.exe is /still/ taking up my whole
CPU. The drive is a...let's see..."Fantom Drives" something or other;
200 GB capacity; 140/186 GB free. Yes, there's a noticable performance
impact (window elements, like the light blue mouseover highlight, react
slowly). Most folders/locations open just fine. On second glance, the
slowdown occurs irregularly, and the CPU usage lingers if I go back to
Computer. I believe that the other location where this occurs is my Home
network drive from my school.
