Unfortunately, that's an ancient artifact of Windows dialog design that has long haunted programmers. The issue is that depending on the DPI setting in the display control panel, the size of the font can change. Or at least it used to; I think I've checked with XP and it doesn't anymore. So that's the deal with that. You can always programaticly set the layout if it's that much of an issue. When I do stuff like frame sliders that needs exact relationships, I just place it aproximately in the dialog template (form), then set it exactly in code.
