Is this a bug? Regarding empty arrays.

The results are correct.

You have an array size:

Width = 10

Height = 1

If you want to empty it, you can set the size to:

Width =0

Height = 1

So how can I find out if an array has only zeros?

You need to loop through each cell and compare if the value equals zero.

If it's a 1D Array use:

If it's a 2D Array use:

"For Y" from (0 to Array.Height-1)
 "For X" from (0 to Array.width-1)
 ----> Array.at("X","Y") = 0
 ----> Else = Stop the Loop

I cannot get the format properly, here is picture, that looks better:
