Details:

Responses from command window went from instantaneous to taking five to seven
seconds. Sometimes the screen dims to indicate saturated resources. Typing the
line '4+3' and hitting return takes 24% to 34% of the resources.

If I write an equation in the editor and hit run and then try to open the
command window, it takes about 3 seconds to open. Execution of the following
took 7 seconds:

H=16;
V=9;

Diag=52;

height=Diag*V/sqrt(H^2+V^2);

In the Linux terminal, it is still instantaneous.
