    I have a program in C# that accesses TwainDSM via twain-cs. I’m scanning with a Kodak i1440 scanner. When I scan 8.5×11 or 8.5×14 pages, it works fine and reliably. The i1440’s automatic page size detection. But when I scan a cashier coupon (long and skinny) my program simply crashes – no error message, no stack trace.

    In twaindsm.log, the last message is as follows, which is pretty useless.

    
    [125757452 dsm.cpp  2368     0 000015B4] Quaero Scanner Workstation -> KODAK Scanner: i1410/i1420/i1440

    [125757453 dsm.cpp  2368     0 00001DC0] Quaero Scanner Workstation -> KODAK Scanner: i1410/i1420/i1440

    [125757605 dsm.cpp  2432     0 00001DC0] TWRC_XFERDONE

    I have tried TWSX_NATIVE and TWSX_FILE with the same result.
