Re: [abc-users] probability

I thought I knew how to generate random numbers at runtime. BUT I dont.
How can make my aspect (or my extension) generate random numbers every
time I run my code. I created a probability PC but generates random
numbers at compile time. This does not what I wanted cause it means I'm
executes the same sites over and over again.
