Best practice. Resizing slider on mouse enter or mouse down?

Hi,
I have my sliders resizing on mouse enter. I am swapping between a larger and smaller slider for a more stable resize. Resizing the slider does also work, but I assume that is not a good idea. Is there a best practice I should be using?
Thanks

It’s not such a bad idea… There’s no fundamental problem with moving/resizing things on a mouse-enter, as long as the resultant behaviour is what you want.

Fantastic news. Thanks
