This does not happen every time, but frequently enough to be annoying. I
click on one of the little triangles in the folder tree in the left-hand pane
to expand a folder, and nothing happens; I get the spinning circle icon and
it sits there for a very long time before finally expanding. I've learned
that I can go ahead and drill down in the right-hand pane while this is going
on, but I'd like to turn off whatever new "feature" is causing this. There's
no physical reason this should happen; this is a Dell Precision 690 with 4
gigs of memory and a very fast 10K-rpm hard drive. When the folders do
expand right away, which is most of the time, it is instantaneous. Running
