The standard Windows dialogue when closing an unsaved document is used by the classic IDE and offers 3 options, ie save changes Yes, No and Cancel and the default is Yes

The 3 options are very clear and the default is to save the changes

However, with IDE 2.0 the dialogue offers only 2 options, Yes and No

The default is still Yes, however, the logic is inverted compared to the standard dialogue and the default is for changes not to be saved, which I feel is wrong

Was there a reason for departing from the standard and inverting the logic ?
