[ERROR] index out of range when reaching end of layers list

[MonsieurRz]

Hello, I would like to say that this tool is very useful, thanks a lot ! This error can be reproduced in a image containing lots of layers (15 layers in my case). In the layer section, reach the last layer and continue pressing down, you will get this error:

panic: runtime error: index out of range [15] with length 15

Second this. In my case at 13:

panic: runtime error: index out of range [13] with length 13

Could you give https://github.com/wagoodman/dive/pull/395 a spin to see if it helps?

I was experiencing this issue. #395 fixed it for me.

I get the same issue (on v0.11.0) but only when using PGDN.
