Thanks folks, I plan to build the installer on Monday giving me the weekend to clear as many problems as possible. I found a major bug today which may account for some of my crashes so I'm hopeful that the game will run reasonably well on your hardware though it's not yet stable. The html manual is complete enough to give you for testing purposes but needs lots of tidying up before release.
Update: Can you see me doing cartwheels. The big bug I found earlier (bad data coming in from a data file) once fixed led me to the root of an even bigger bug which caused my game to crash just after ejecting unwanted cargo. Another one down. Perhaps it will be stable sooner than expected
