Build 1944. Unless I missed something the new TesterStop() doesn't work well with Genetic Algorithm. It is trying again and again the same "stopped" passes :

There is some problem with OnDeinit in MT5 build 1940 . When you call a simple function with a loop to delete graphical objects the platform freezes for a few seconds and fails to delete all objects.

With the code below you can reproduce the bug.

string objName;
string uniqueid="XID: ";
