Hello:

I have a Form that override the OnClosing method to make some actions before
the window is closed, but does not set the Cancel property to let the form
close, assuming that its value by default is false. All was working fine
until I install the service pack 1 of the .Net framework 1.1. The Cancel
property is true and the form remains open. I change my code to assign the
value to false, but I want to know if there is a reason for this behavior.

I check on a new application calling the Close(); method, or clicking on the
close button, and try also with the application main window and with another
window, modal and modeless, in all cases, Cancel property was set to false.

Somebody has an explanation?
