Normalize going CRAZY. Anybody have solution?

I have asked before, but never received an answer from SF, so I though I would seek out you experts.

I just tried to normalize an entire project, a wedding. Wanted a ceiling from which to work. I selected the first clip of the project with audio and then selected SELECT TO END. I then clicked on Switches and clicked Normalize.

At first glance, the first part of the project looks fine, and the end looks fine, but there are a few separate places in and around the middle where the audio wave actually FLAT LINED. There is now no sound, at all, where there WAS sound before I normalized.

Investigation into View\Edit Details shows that everything is normalized.

Clicking on any particular clip that is flatlined shows it is normalized.

Clicking on any flatlined clip and turning OFF Normalize brings back the original sound.

This is not the first time I have seen this happen. It happens EVERY time I try to use VV3.0c to normalize an entire project.

What gives?

I can't get the flatlined places to display a wave unless I turn OFF normalize, and even if I turn it back on, some other place seems to go flat in response.

Any ideas?

An experiment springs to mind, if you're willing to spend a bit of time trying something ...

Load that troublesome sound clip and Split it into two roughly equal halves, normalize each half. Does one half work and the other half flatline? If so, delete the half that works, turn of normalizing, split the remaining half into two sections, normalize both, etc ... If you see that a smaller and smaller piece of the clip is causing the problem while the rest works, i would guess there's a bit of data in that small section that the normalize function is having trouble with. If you get this down to a very short sample, open the clip in SoundForge, copy & paste that section (probably at least a full second on either side) into a new file. SonicFoundry's Dr. Dropout would probably be interested in examining it closely.

take the problem clip, trim the right edge in a little, then back out, toggle normalize off/on- still flatlined?

What do you mean by "back out?"

Drag the right edge of the problem event to the left, then drag it back to the right to the original position, the un-normalize/re-normalize. Still happening yes/no?

Interesting, I can't get the single clip to fail NORMALIZE today.

HOWEVER, if I pull ANY captured clips, from my most recent, recent or old captures, into a brand new, clean timeline, such that AT LEAST TWO of them go off the screen on the right, then I can consistently produce a flat line. It always starts with the first one completely off the screen on the right, but for some reason, if there isn't another second one (or more) behind it on the right, it will not flatline.

Very odd.

There is NOTHING else on the timeline, I am using VV 3.0c bld 138.
