i think the problem is that you do not get the basic concept behind how a computer works. it is impossible that 2 or more scripts are running at once. a computer does one action after another, one line of code after another. you cannot tell one trigger stop the other trigger because no other trigger is running that time, no other action is performed.
all you can do is set some variable and check in your other triggers the value of it to determine the further actions.
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
