As I mentioned before, it could be your DPI (dots per inch, or PPI for pixels per inch in some other countries/regions). Check your monitor settings. Since you're using pixels for both GraphicsPaths I don't see how this would be a problem, though, so long as you have no form border. The Framework itself is agnostic to the platform (for those classes - like most - that are supported by every Windows platform) so its settings on the machine that are affecting your Form. Without being there on your computer it's hard to say. This posting is provided "AS IS" with no warranties, and confers no rights.
