The Google Photo Screensaver, AKA the Picasa screensaver displays a weird behavior on my laptop: sometimes it works just fine, but lots of times it starts for a second or two, and then it stops, as if somebody touched the keyboard.
It feels like the very act of starting the screen saver is doing something that makes it "wake up". Maybe I'm just anthropomorphizing.
I don't have this problem with other screensavers, and the Picasa one works just fine on my other computer.
Has anyone seen this? How do I troubleshoot it?
I have a Lenovo T43 with Windows XP SP3.
Update: I don't know if it's relevant, But the laptop is connected to a TV via s-video. The screen saver starts on both screens (whether it successfully starts or not).
