Hi,
Recently I posted a query here about whether it was possible to run multiple versions of IE on a single Vista installation. Seeing as no one knew of a way of doing this (without virtual machines) I thought my discovery may be of use to someone.
I came across
IETester completely by accident, but it does an awesome job of putting the rendering engines of each version of IE into one interface, which works fully on Vista.
Its verson 0.2 and crashes a lot, but I’ve saved a shed load of time already cross-browser testing.
Hope it’s some use
