This error occurs almost every time I build a DataGrid View with few columns
(~1 to 3). My current code crashes everytime in Mono and never in VC#.
Unfortunately it is too heavy to be sent as-is and I don't have time to send a
test-case. In case it can help in the meantime, the exact exception I get is
(indeed related to MoveCurrentCell):
System.ArgumentOutOfRangeException: Argument is out of range.
Parameter name: y

For your information: I'm running Mono 2.6.3 under OpenBSD (I know... I
know...)
Mono JIT compiler version 2.6.3 (tarball Mon Apr 12 14:41:35 MDT 2010)

        TLS:           normal
        GC:            System Boehm (with typed GC)
        SIGSEGV:       normal
        Notification:  Thread + polling
        Architecture:  x86
        Disabled:      none

PS: I think the priority should be raised, since in simple and normal
conditions, the code crashes with an exception that is not expected to occur.
