Hi
Thanks for the report. Windows Vista has driver issues. Greyhound Manager uses an older version of dirctx which is supposed to be fine on Vista but it's all down to individual video card manufacturers providing the drivers. I am fairly sure this will be the problem but am logging all vista related reports and will look at these after the game has been on sale for a while. For now please submit an error report to
support@greyhoundmanager.com. I am presuming the graphics mess is the first screen you see? Please provide any more details you can think of.
For now, anyone with Vista should obviously try the demo first and make sure it's running ok.
