There are some ensembles in Reaktor which involve working with samples, for example Beatslicer (in New Additions->Sample Player). Here, there is a bar above the sample window which shows the directory path of the sample being worked on, and to load a new sample you right click it and a menu appears enabling you to access a file picker. This works perfectly in standalone Reaktor. However, when I load Reaktor as a VSTi in Sonar, nothing happens when I right click on this bar. Therefore there is no way to load a sample. There are a few other ensembles which also require right clicking to load a sample, and it's the same deal: works fine in standalone, totally disabled in Sonar.
Does anyone have any ideas?
