Game Progress Reflection...

This week I learned how to do the Drag and Drop but when I started to do it I kept accidently moving the screen so the circles and stuff cut off some how and I kept having to start all over. I was trying to do like when you drop it in the correct place it disappears but I messed it up again so it was hard. When I finally got it I exited out but I forgot to save it so I guess I got far in some way. I am super frustrated because each time I fuigure out how to do something new in flash i either forget how to the next day or mess it up.
