1.) .rld global doesn't work. There's no way to reload data for ALL symbols, you can only do it one symbol at a time and it's a real pain in the behind.
2.) if you have a scanner linked to a chart and both have different datasources, clicking on the scanner symbol will force the datasource on the chart to be the same as the datasource on the scanner.
this bug was just introduced in beta2, as it worked fine before.
