arionum-gpu-miner seems to quit for some batch numbers...
but it also has different intensity for cpu and gpu blocks, -b 48 -t 1 on GPU blocks is fine with minor UI lag, but on CPU blocks it just makes PC stutter like hell
totally unusable for desktop, if you have a dedicated mining rig then yes, you don't care, so please leave with your "everybody is happy with the mining software", because at least 1 doesn't.
currently only ariocppminer works perfectly, but it's only for CPU
