I have a new Mindjet subscription. I like it very much but have a question about opening a Mindjet map (stored on Mindjet's site in my account) on several computers at the same time. E.g, I work on a file on one computer and, when leaving, forget to close the file. I then open the file (using my same login) on another computer. I CAN open it and edit it, but the files open in the two locations are now different. Also, if I try to open the file from my iPhone (when it is checked out in another location), the file is shown as locked. I can open it and change it, but then I'm prompted to save it as a separate file. Is this the way things are supposed to work? Is it necessary that I ALWAYS close the file in the location at which I'm working before I can use it at another location? I'll be happy to share my workflow if that will help.
