Is it possible to use the standard windows file browser dialog?

The custom control dialog doesn't paint correctly (arrows disappear, background missing), so is a royal pain to use, and it is so slow to draw.

I've been playing around with the UI settings.

I've changed style to none under Preferences > User Interface > Appearance > Colour Theme Mode

This has removed the styling from the dialogs, which is much better. The only drawback I can see at the minute, is that there are no toolbar colours now. It's also improved the overall performance of the UI paint.
