well) i just find a decision) it s not beautiful but hope it works) i just made one bat file to start miner and another one that counting down 15 minutes (for example) and killing miner process in task manager/waiting for couple seconds and starts first bat again in new cli window) and starts counting again. this rough thing hope will help from hanging and other problems)
why all the trouble? V1.4 exit's miner in case of connection problem, so u can use it, frequent miner restart looses profit because of the time takes to send first share after miner start.
V1.4 should be better in this case.
I will try to check if something changed in ccminer v2.3 in this matter.
