mouse wheel zooming problems

A recent change makes the map not stay centered when I zoom in/out using the mouse wheel in K-Meleon 1.5.3. It's an old browser (based on Mozilla 1.8), but this probably means that something's wrong with the code.

PS: double clicking with the mouse does work. So it's still able to detect the mouse position; it's just something wrong with the scroll wheel code.

What do you mean by "stay centred" exactly?

I can't remember offhand exactly what OpenLayers? did, but Leaflet seems to be behaving reasonably as far as I can see - it ensures that whatever point I zoom in on with the scroll wheel stays in view as I zoom in.

I've tried the old OL interface now (it's on and it seems to behave in much the same way as Leaflet and keep the point the mouse is over at a fixed point in the view as you zoom in.

Yes, it does work properly in currwnt versions Firefox and IE. Both of those are more bloated than K-Meleon. Until the recent change, it worked fine in all those browsers. I see no improvements, only a slight difference in UI, so why was it changed in the first place?

Because somebody submitted a patch to change it and the consensus was that Leaflet is an improvement - it's smaller and works better on mobile devices.
