MS released a new Application Compatibility Toolkit to evaluate compatibility with Vista yesterday. It can be used in Win2k and WinXP
Not sure if it is of any use, but here it is: http://www.microsoft.com/downloads/d...playlang=en%20
That program is more for checking if the installed programs are known to work fine after OS upgrade / Windows update. It is not checking for bugs or so in the program or OS itself.
We will try to test Graal soon on Vista.
