This problem also affects the matrix and row operations tools. So I have put up alternate links to those that bypass NCSU altogether.
Summary: if you start at the above link and use the links you find there to access the Row Operations or Matrix tools, I believe things will work fine. Do report any continued problems.
Since this may have affected students working on tonight's homework, I have extended this homework (due Sept. 24) for an additional day so that it's due Sept. 25.
