Clearing the Mathematica preference files solves this problem. Instructions can be found here: support.wolfram.com/kb/12464

Ok, that helps. Thanks. I would still like to know why ctrl+c does not work and if one can fix this.

comment Using OddQ and EvenQ in piecewise functions: Buggy?
@wolfies: I was merely stating that OddQ behaves as documented. In fact, there is even an example in the documentation, which shows that OddQ[x] gives False for non-numeric x. This design decision has the advantage that functions of the form *Q always return boolean values and If statements evaluate.

comment Using OddQ and EvenQ in piecewise functions: Buggy?
@wolfies: The documentation states that OddQ[expr] returns True only if expr is an odd integer.

comment Evaluate as much of an integral as possible
Your question is quite vague and subjective. In what sense is the right integral "more integrated" than the left one?

comment Pattern matching using Cases: why does this fail?
I changed my reply a bit. Those patterns with default values are neat way to simplify code, see the tutorial on Patterns and Transformation Rules.

comment Pattern matching using Cases: why does this fail?
Did you, by any chance, use exponentiation in your last line of code (in Cases)? Because if I use exponentiation I do get an empty list, while using Wedge returns the desired terms.
