Expert Problem On Multiple Charts.

 
In examining problems with an expert I designed, I activated the expert in multiple charts. Within the expert I established a line of code that alerted me to some variables within the expert. I evalutated the results I obtained from a custom indicator with results I was getting from the printed variables coming from the alert function. What I discovered was that when I removed an expert from a chart, it continued to supply variable data in my alert function. Does anyone know why the expert in the chart did not stop? Do I have a defective program?
 

each chart = own environment

each EA own program/instance of .ex4

2 attach EA abc to 4 charts u do 4 times/runs/dbl-clicks on default/visible chart - doing this attach on each chart,...

2 stop absolutely ALL instances u must kill off all by selecting each chart in turn and remove from 'that' chart, then repeat,...

so - u have 4 programs running not 1, so u get alerts until stop all 4
