Can't move multiple blocks?

When selected together, blocks seem to become unmovable. Manually drag-dropping such a selection de-selects the non-first blocks (to move only the first single block), and the “Move block up/down” shortcuts don’t do anything to the selected multiple blocks. I’ve searched for this problem in the forum and haven’t found a mention. Am I the only one experiencing this?
