So, it turns out it is has nothing to do with your recent changes. I've seen this problem before on OS-X but since I don't use my mac much these days for dev work I had forgotten about it. Basically, with some drivers, if you try and specify them at the command prompt with "./example/x -dev driverx" then they will give a bus error. However, if you just run "./example/x" and the choose the driver from the list everything works. Since this issue has been around for years and I'm the only one who seems to struggle with it I'm not inclined to delay the release until it gets sorted out. -Hazen ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
