New Post: How do I update a preview window from imagemagick?

This is the error thrown:

Exception thrown: 'ImageMagick.MagickCoderErrorException' in Magick.NET-Q8-x64.dll
Exception type ImageMagick.MagickCoderErrorException
Exception message: WriteBlob Failed `foo.png' @ error/png.c/MagickPNGErrorHandler/1650

Line 88 is the result.write, but the file itself writes fine as i can go to explorer and see the changes went into effect, i cant reflect the changes in the panel control. how do i go by updating hte panel with the same file, as using a temp file, disposing, cloning, or increment a timestamp as a suffix seems like a cop out as there should be a more correct way of handling it (or at least more elegant)
