If you supply a default name, the name portion preceding the file name extension is selected, preserving the file type extension. That works well.

This works on OS X but not Windows. On Windows the entire file name (including extension) is selected. If the user just starts typing away then the extension is lost. This seems to be the standard behavior with other Windows applications but see below.

OS X allows the developer to supply a file extension, and Rev provides a means for doing that. But apparently the OS doesn't prevent the user from going out of their way to delete file type extensions in its dialog, and the "ask file" command (when used outside of the Message Box) faithfully returns exactly what the user entered.

I just tested Notepad and SnagIt on Windows. The behavior in ask file dialogs is to automatically append the extension of the currently selected "Save as type:". In Notepad I tried to save a file as "test" in a folder that had a "test.txt" file already. I clicked the "Save" button and was immediately presented with a dialog asking if I wanted to replace "test.txt" (ask dialog did not disappear).

So on Windows I think the file extension of the currently selected "Save as type:" should be automatically appended to the file name. On Mac I think the current behavior is correct since file extensions aren't required.

The fact that lots of us are writing cross-platform software means some of us might want to enforce file extensions so the files can travel between different operating systems easily enough. Maybe an option to force the extension on OS X would be nice as well. We can do it manually now but it would be nice to not have to add the extra code to check each time.

Those are important observations. Please consider adding them to the BZ report at:
