Just downloaded the trial version on my laptop and desktop. Desktop (win10) seems to work ok, laptop (win7) which I need for imaging had problems. If I move a module by dragging with the mouse, it vanishes. Left click and it appears in the new location. Similar problems all round-- one click to initiate the action then a second to make it work.
Another problem is trying to open a file; if I select file>open, the browse window is under the already open windows.

OK, the old reinstall trick seems to have worked.
