I am entering a few of my old brew day notes into Bru'n Water to get a feel for how to use this program and compare the estimated results to my actual measured results. I can't seem to figure out how to enter anything into the desired water profile. It won't alow me to enter any nubers into line 4 at all. I've even tried to copy and paste from the profile chart below. I'm using version 1.9 with the free file opener. I'm starting to wonder if the free file opener is not allowing the program to work properly. Can anyone help a brutha out?
