do you update the miners to the latest version?
also i do not see the algo for skein. is it possible to add it?

I had this issue once.
go to config.txt and try setting "@@DELAYCLOSEMINERS=20" to "0" seconds.
it should be fine after that

I think it is due to the fact that when it runs profitabilty algo, the old miner window did not close therefore you have both miner windows open at the same time.

hi,

I currently have 2 nvdia cards but i am running the old one for display only and the other to mine.
however when i start megaminer, it groups the 2 cards together and start the benchmark.
Is it possible for me to disable the old card so that it will not be run for benchmark and only run benchmark for the new card only?
