middle mouse button issue, is this a bug?

I have code to control the 3d camera with the mouse.

The middle button, mouse scroll wheel, is used to zoom in and out.

I use the conditions "on mouse wheel up", and "on mouse wheel down", to determine if it should zoom out or in.

The problem is when the right mouse is held down to rotate the camera, the middle button wont register at the same time.

I can use "middle button is down" instead, which will regiser, but that doesn't determine the scroll direction.

Is this a bug?

Can you post an example? Because it seems to work just fine on my end. Maybe it's a browser specific thing?

Thanks for checking. I'm wondering if perhaps its my cheap mouse thats the problem.

I do some tests.
