Mathcad 15 stops respoding
Every approximately 10 times I start a Mathcad 15 session under Windows 7 it ends with "mathcad not responding". I cannot close Mathcad, Task Manager cannot close Mathcad, but mostly I can stop Mathcad in the process window by ending the process. Does this happen to anyone else or am I a lone sufferer with some computer/operating system glitch? This often happens when I have been editing e.g. plots.
