Hi everyone,
The SaveDialog option OnOverwritetePrompt default setting is False, which I believe should be set to True by default, on the Win7 installation 0.9.30.4
If this is confirmed, I'd recommend that it be set to True for a new installation.
Otherwise, naively clicking on any file shown by the dialog does the saving in a silent mode.
My earlier version of Lazarus (XP a year ago) I never had to change that setting, and it worked in the familiar way of the Windows system, i.e, prompting if one wishes to replace the existing file.
