I'm using Opera 31.0 on Windows Vista Ultimate 32bit and Opera crashes on me on a daily basis. It freezes on me several times a day until it finally crashes (blue screen) and restarts my computer. It really sucks. I've been a faithful user of opera since its beginning and I must say its quality of performance has really gone down hill. And, please don't make any remarks about vista being the problem cause I'm not buying it.
