I am running Ver. 30 of CD in Win 8.1, on a new HP desktop (Pavilion 23 PC) . In a word: Spectacular, for my needs. Thanks, but still looking to the next update!
Cheers :-TU.

PS. Ver. 31 is excellent.
Comodo Dragon is really nice. Glad Comodo develops it. 
I am with you guys. :-TU
It has been my default for quite a while now, it is so easy to temporarily forget others exist.
