I got the newest version of IB Gateway, necessary Asset subscriptions with IB are in place. Moreover, Multicharts .net downloads the prices from that same IB Gateway just fine.

I invite you to take your favorite asset list and see for yourself:

Code:
function run()
{
  NumYears = 10;
  assetList("History\AssetsMinutes.csv"); // load asset list
  while(loop(Assets))
    assetHistory(Loop1,1);
  quit();
}


Seems to be a problem with Zorro after all.
