Hi There, i'm new to mining in general i was using another program but i'm more comfortable using winminer, its great and i wanted to say congratulations!

but i wanted to ask a question, sometimes instead of mining it just says device detected ( i can see that its using 100% of my gpu ), but not telling what coins is being mined neither how much is my estimated earnings
so should i just let it continue its fine and its still mining ? or do i have to restart it  ( stop - start again ), ?
because if it means it stopped mining or its a bug then i can't leave it overnight for nothing so what i can do ?
