Astroid megamenu header and sticky header misses cursor: pointer (CSS)

Hi there,
I am wondering: I haven't changed any thing (as far as I know), but my mouse cursor in the header navigation suddenly only shows an **arrow** (instead of the pointer finger) on a href. In another projekt with same Astroid version I have the **pointer**. Is there an adjustment anywhere? Or do I have to adjust the CSS anyway?

Thanks a lot!
