Why doesn't "Screenshot" make it clear that it is in VIDEO mode?
I did something or another to put it into video mode. There is no obvious way to put it into or out of that mode, so once I've stumble-fingered my way into that mode, that's it. I know that most of the folks here are customers and not Apple folks, but they do wander by. If you are an Apple person, FILE A BUG REPORT. User interfaces that are user unfriendly are BUGS.
P.S. Ten minutes later and I still haven't figured out how to get it out of video mode.
IT SHOULD NOT BE THAT HARD TO FIGURE OUT.
See if deleting these two files helps
~/Library/Preferences/com.apple.screencapture.plist
~/Library/Preferences/com.apple.screencaptureui.plist
Nope. Not useful. It's still in record mode.
