close the anim playback window
…
and also check you render output directory
//render/
is good, it is the render directory in the current working directory (if applicable the directory of the file you have open)
Render directory is /tmp/ (i’m on linux); the anim playback window wasn’t open.

Rangel
or if you’re in windows explorer thinks it has opened it (to try to create a thumbnail or something stupid)
