On Vista, I got a problem with the application crash handler. Basically, if something unexpected occurs which cannot be captured by SEH, I get this pop-up window with "The application stopped working", blablabla, "Close program/Debug program" -- that is, after I disable the error reporting using the system control panel. With error reporting enabled, you would get a task dialog with search for solution online, close, debug.
This is not so funny if it happens in automated tools, and I wonder whether there is a way to get rid of it totally, read, if my app crashes, it just crashes to the command line or disappears but does not bring up a dialog.
