#69 Automatically close popups when leaving page

[Patrick Wolf]

Automatically close popups (eg. lov, date picker, ...) when leaving the page or when the browser is closed.

It doesn't really make sense to keep them open, because they can't write the result to the new page anyway and it may only distracts the end user.

Another side effect is a problem with checksums, see
