Topic: Occasional bug with '-' sign before constants

Trying to enter a function y=1-e^(-x) gave internal error AAFACE. Changing that function to y = 1-1*e^(-x) gave no error though. This bug happened several times occasionally (not every time), so the source of it might not be precisely the '-'sign.

Re: Occasional bug with '-' sign before constants

I have not heard about such a problem before. It sounds very strange. Unfortunately I am not able to reproduce it. I will look into it, but until I can reproduce it I am afraid I will not be able to fix it.
