quite frankly from my personal experience , i gave up on mindmanager 'forums' when last year I struggled on the PC forum to allow them me provide the cab file so that I can embed that in a webpage and be able to view my mindmaps locally on any computer , none of my q's were answered.

No doubt it's an awesome software.

As for cross changing platforms and people who travel between pcs at home ,macs at home or office, i would suggest u to try www.mindmeister.com , it's basic ,but gets the job done stores the maps online too. there implementatino of notes key (f2) is bad otherwise it's a very very good tool
