Two bugs in Rev 6975

[Peter Van Roy]

The first bug is in CAS Mode:

Code:

taylor(sum(xˆ(c+1),x,1,b),c,5)

gives a complicated term starting as:

Code:

b*x+(...)*c+...

The problem is that this term should not be a function of x.
Note that x, b, and c are all unbound variables.

The second bug is in Home Mode:

Code:

sum(Xˆ1.01,X,1,1000000)

Let this run until the display dims (after around 30 seconds).
Touching the dimmed display puts the Prime into a blocked state.
(Note): This must be entered with Sigma symbol, using sum gives invalid dimension error.
