Hello. I'm using a trial version of MJ online. The button "Export" in the menu seems to be functional but it doesn’t really work. When I press it, a dialogue window appears asking if I want to save changes or not. If to choose NOT, nothing happens at all. If to press YES, it is processing a little, then nothing happens either. So, is the function "Export" in this trial online version supposed to be active? Can I export a map to another format?
