Hi, > How do you even manage to run a D5 Windows > application on a Mac system anyways? Is that > even possible and if yes, how?
The latest Macs use Intel hardware and can run Windows in two different ways - Windows can be booted directly using Boot Camp, or it can run in a virtual PC created by Parallels Desktop. My D5 Windows app runs fine in both environments apart from one aspect -- multiple monitor support via TScreen.Monitors[], TScreen.MonitorCount and TMonitor. Accessing these on a Mac produces the dreaded "encountered a problem, Windows needs to send a message to Microsoft" response. I need to determine if the app is running on a Mac, and if so disable multiple monitor support. So the question is -- how to find out if the app is running on a Mac? Alternatively, how to use multiple monitors in Windows on a Mac? Many thanks for any help. regards, Martin.
