Drag-clicking on checkbox/buttonset doesn't register as click

The problem happens when using .buttonset() on radios or checkboxes, or just .button() on a checkbox.

If the mousedown occurs on the button, then drag (a little or a lot), then mouseup while still over the button, the button will not get clicked.

(Those are straight from the jqui examples)

Since these are buttons/buttonsets, I believe they should behave like them with regards to these drag-clicks.

Some people also have "sloppy" clicks which might drag a bit before the mouseup, and then it doesn't get clicked as they would expect (and then they blame me! otherwise I probably wouldn't have filed a ticket)

Cheers!
