I have a clone, and I want it to point at its parent sprite, but this can not happen because the parent sprite is not in the drop down.

Here's how to get around this problem:

Go to another sprite (or create a new sprite and select it).
Drag out a “point to” block and select your parent sprite.
Drag that block to the parent sprite and let it go.
Select your parent sprite and you should see the block you want.
Shift-click on that block to create copies of it as necessary.

Clever

Thanks.

I had to figure out this problem when writing my clock project. The Go To block has the same limitation.
