Minor Problem with Hyperstack

[karo03]

On my Mac (PPM) I have a minor problem with an hyperstack.

ImageJ 1.41n (daily build, Java 1.5.0_16)

Clicks into the lower right triangle does not move to the next Z-stack  
image?

Could anybody verify that? It can be tried with sample image organ-of-
corti!

Thanks in advance
