As you may know, the company which developed the Micrografx Designer was bought by Corel in 2001. So the developers could have integrated into the Corel portfolio the functionality of Micrografx Designer. I suggest you use the latest version of the Corel product, which is fully compatible with Windows 8 on 64-bit, to help you with your problem.
