As a matter of fact I have two versions, TRS MAC 1 and 2. They're just not registered, that's all. What I meant is that on an iMAC, none of the problems they are talking about above ever happen. Those sorts of things only happen on Windows PCs. With an iMac, you can force close an application anytime you want, shut the computer down by pressing and holding the power button, even pull the plug out, and it will automatically save what you were working on, close all applications properly and shut the computer down in the proper way, and it does all that in just a few seconds. Let's see a Windows PC do that.
This issue don't have anything to do with this being Windows. It's the older version of the software which is a 32-bit application. The new version, T: ANE, will not have these system and memory limitations because like the Apple version will be new and make use of the newer hardware and operating systems that are available today. I'm not sure if you are aware that the very first Trainz version came out in 2001 and all subsequent versions are based on that as a code base. We also have to remember that there was no 32-bit or 64-bit home operating systems. In the early days, prior to Windows Vista even, we only had 32-bit Windows for home. There were 64-bit Windows versions, however, they were used on servers and high-end workstations which wouldn't run games anyway. When Vista came along, there was a push to make use of the capabilities of the new processors which were 64-bit, and this has been the case ever since.
So your Apple versions are based on newer, updated code which hasn't made it to the PC platform yet and we will see this with T: ANE.
