Hi, I'm running mathcad 14 with parallels 9 on my macbook pro, but the problem I have is that mathcad doesn't solve 10x10 matrix or bigger. I was trying to transpone a 10x45 matrix and mathcad does nothing, just shows two little black boxes, but when I try with a 9x9 matrix, mathcad works perfectly. So maybe some of you have had similar experience and could help me. Thanks
