Summary:  compiler does not find error, runtime prints strange message

Original Submission:  If you add a handler for an event to a widget, and that 
handler has the wrong signature, the compiler blithely continues.

The eroneous code assigned to Click using += new EventHandler(handler),  but 
the signature of the handler is (object, PaintEventArgs)

When the program is run by ilrun, this message appears:  EditWindow::.ctor 
[2129] - call at verify_call.c:1089
Uncaught exception: System.Security.VerificationException: Could not verify the 
code
        at CqlJournal.EditWindow.Main(String[])

Code to produce this error:
TextBox tb = new TextBox();
tb.Click += new EventHandler(myHandler);
.
.
.
But, myHandler is not of type EventHandler.  The method that produced the error 
pasted above is:

private void myHandler(object obj, PaintEventArgs args)
{
...
}

file that demonstrates the problem.  It isn't the simplest possible case, but I 
included it because (1) it produces the error I pasted and (2) I was feeling to 
lazy to make a separate test case file.
