"Levels" keyframes timing messed up in MediaFX

I'm doing 2-cam multicamera editing in Vegas Pro9c. Both camera tracks start at exactly the same time - no offset.
I'm keyframing some "Levels" in one track. The keyframe timing-effectivity is behaving completely wrong: For example, I place a keyframe at 1 minute, 30 seconds, and then another one at one minute, 32 seconds - my intention is to lighten some footage that comes after the 1'32" point.
The keyframe at 1'30" retains, as it should, the value set in the PREVIOUS keyframe at the beginning of the track. But if I change the Levels value in the 1'32" keyframe, it affects the lighting in footage EARLIER in the track -- at 1 minute, 10 seconds.
This is not the way it's supposed to work. Has anyone else experienced this, and hopefully knows a way to make it work the way it should?

Zoom the keyframe timeline on each keyframe to see if there is an extra keyframe somewhere that is not visible when the timeline is zoomed out -- or look at the very end of the timeline --- seems that there is an extra keyframe that is causing the behavior.

Thanks for the reply.
Yes, I had checked all of those possibilities.
I even started from scratch (twice), making absolutely sure that there were no extra keyframes. Even tried it with a completely different project than the one I had been working on. Same result every time...
Put in a pair of keyframes early in the timeline and set the values I wanted.
Put in another pair of new keyframes later in the timeline, and still found that changing the Levels value in the VERY LAST keyframe affects the light in the video between the FIRST AND SECOND keyframes.
This used to work properly, but doesn't anymore-- and of course, it makes multicamera postproduction many, many times more tedious.
I tried opening up Vegas8 and repeating the experiment. Same result.
So it's probably not a Vegas issue, but something deeper-down, though I can't imagine what it would be. The only changes to my WindowsXP Pro system recently have been a flurry of "security updates" from Microsoft. Possibly one of those updates messed up something that the Vegas application depends on.
Who knows?
I'm at a loss, as to how to deal with this problem.

Can't repro. Working as expected.

Thanks for checking, Grazie.

I'm pondering a new Win7 computer... though dreading the thought of dealing with all of the many applications I run in my very-multitasking professional life!

I've heard of a "Move My Computer" utility, but if I go to a new machine, I'll probably spend the 2 weeks or more fresh-installing everything, rather than risking moving possible Registry problems to a new system.
