Using MYOB for Windows on Mac

HI Guys, Just hoping for clarification. I have been supplied with a MYOB CD for Windows for a uni course I am completing and understand that I would need to partition my HD on my MacBook Pro. But all my other files and assessments are on MAC. If I set up the partition, am I correct in saying that I won't be able to switch between Mac and Windows seamlessly, without re-starting? If that's the case, Is it just worth buying Crossover so that I can still have my Mac files open whilst using MYOB?

Any clarification would be greatly appreciated.
