Hi, Rob, I cannot seem to duplicate your error with the multiple popup windows, can you take a screenshot showing the popup windows together with the alert message on the popup so I can identify which one is doing this?
Regarding keeping alerts active, this will turn off all alerts once one has been reached, an improved feature would be only to turn off individual alerts.
the multiple popups should not happen, we can fix this if you can provide the information. make sure you are not backtesting.
