Viewer just went white

Hi all: I have dozens of clips in my timeline and I have been marking the ins and outs and converting them successfully to a different format (going to EXPORT, QUICKTIME CONVERSION). After about 3/4 of the way through, my Canvas just went white. I can scrub through the timeline and hear the audio but there is no video in the Canvas. I opened up another Project and imported some of the clips; same thing. This is wierd, never happened before. Any ideas why this might have occurred? Did I accidentally hit a key I should not have?

FCP 7
OS X 10.6.8
Intel 2.16 Core 2 Duo
3 GB SDRAMM

Above the canvas monitor there's a drop down button with a square in it. Click that.
You PROBABLY switched to Alpha from RGB.
Make sure it's on RGB.

In 20 years of editing in FCP I have never done that before. DAMN, you guys are good! Thank you.

If you look up whatever the keyboard shortcut is for that, you were probably mashing something similar at the time.

I was mixing together Avid and FCP. Been editing as a combination 19 years now, not all FCP. I stand corrected.
