Exposé doesn't show the window I choose

Question

When I invoke Exposé and click a new window, Exposé ignores what I clicked and returns to the last active window.
For example: let's say I'm using Safari and I have Mail open in the background. I invoke Exposé and click on the Mail window to change applications. But instead of switching to Mail, my OS just returns to the Safari window, as if I clicked it instead.
(I notice that the blue highlighting doesn't respect what I click. It remains on the window that's active. As if it doesn't see what I'm selecting. Sometimes the highlighting will briefly, correctly, appear over the window I'm actually trying to select—but then it moves back to another window.)
I have tried all the fancy reboots I know, and I have even reinstalled my OS (not a wipe and install, but a reinstall—hope I did it right).
Anyone got any ideas? Thanks!
