onHide event not firing

I have a form called Proposals with four tab panels.

If I move from one tab panel to the next, the onHide event fires on the tab panel forms as I would expect.

BUT, if I change a peice of data in one of the fields on one of the tab panel forms and then click on another tab, the onHide event doesn’t fire.

However, if I change a peice of data and then move to a different record on the same form and then click on another tab, the onHide event does fire.

Any idea what I can do about this???

Hi Glenn,

Can you send me a sample solution?
