Function App: Fcn Signed area hangs on calculate...
I was checking out this thread and may have run into an issue with Fcn signed area
http://www.hpmuseum.org/forum/thread873.html It seems to be a special case** in Function app where: F1(X): e^X then Plot Menu Fcn Signed area from say 0 to 5 shows 147.4 quickly, but f(x):=e^x; Function.F1:=f; then Plot Menu Fcn Signed area from say 0 to 5 hangs at "Calculating..." ** Either method seems to work with f(x)= x, sin(x), ln(x) but hangs with e^x

If you edit F1 in the function app, do you have the lower case exponent x? If you change that to upper case, does the problem go away? (As in CAS view vs. Home view variable assignment).

(As in CAS view vs. Home view variable assignment). Both cases show e^X in F1(X). Only the case where F1:=f is used first causes the hang. Hopefully someone can recreate this or offer a solution.
