1. Use left-click for foreground annotation on the firts frame
2. Click the "commit to permanent memory" button
3. Click "Propagate forward"

then I got the error info below:

Is there something wrong with my operation?

This seems to be a WIndows specific problem. Let me see if I can fix it.

[HyperTwo]

OK, I try to run it under WSL

[hkchengrex]

I have pushed a fix for Windows that limits multiprocessing for dataloading. Linux system is still recommended as it will be faster.
