hi,
after installing Siverlight v5 as asked by Kiosk, it took sometimes a very long time to launch (around 5mn) freezing my system, especially when i switch from tablet mode to desktop mode and vice-versa.
Anyone observed that.
I think you should place a bug report
mine is lightening fast.
i found on the bug thread someone having the same issue, i forgot to precise , i am on a laptop too.
