I though DOS boxes in Windows 2000 and XP were really just system command lines. I'm sure I/O is virtualized for DOS applications, but does this also affect native 32-bit apps? If XXCOPY is a proper Windows 32-bit app, it should work just like any GUI app, I'd assume? -- Hector Martin (hector@marcansoft.com) Public Key: http://www.marcansoft.com/marcan.asc -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
