It is too easy to create spurious event methods in form code just by double
clicking on a component on your form.  It needs to be easier to remove these
unwanted methods.  For example, you should be able to clear out the event handler
name in the properties sheet on the "Events" tab in order to remove the method from
the code.  Currently, you must click the ... button and then select the
method name, then click the Remove button, the OK button and then the OK button
on the warning message that appears.

It would be fine to have a warning message when you clear out the event handler
name in the properties sheet, but the warning should really only appear if there
is code in the method that you're going to delete.  Otherwise, the message is
not necessary.
