I've downloaded the free version to have a play. Installed in a W7 VM.
Overall it seems quite good but the visual aspects of form design are disappointing. Each time I clicked on the component palette the form disappeared showing the code view and then came back. Dragging components around on the form results in a "tail" of images which is quite disorienting.
Are these problems present the paid for versions or simply something to be improved in the future?
