Windows 7: Lock screen after specific app quit : How to?

I looked at this thread last night and was debating whether or not to have a look due to Goja's attitude but today I decided I would have a quick look before I checked this thread, which I now see he has been banned but I thought I would post my info anyway.

I now can't verify if "AlbumArtScreensaver-1.0.1-beta13.exe" from "Crayon Room - Album Art Screensaver for Windows" was the screensaver he was trying or a good alternative but I have read his other thread - Album Art Screensaver on x64 system, fix it? Or any alternatives? and it looks the same as the one Bongo tried, post #3, same info in the About box, bottom right.

Anyway I installed it in Windows 7 x64 and it worked just fine, the same as any other screensaver even though the .scr file was in SysWOW64. I didn't actually test displaying album art because I was only testing if it could be selected under Personalize > Screensaver and the timeout worked, which with a 1min timeout it worked.

Even though Bongo also had problems in the other thread, post #13, I came to the conclusion that if it was this screensaver then there is another reason why it would not work, not x64 incompatibilty.

Too bad Goja did not have a better attitude.
