The attached program tries to save a blank 64 x 64 TIFF image to specified =
path.
When the path specified is local, the images saves fine.
If the path is on a network drive on a Windows7, then it saves a corrupt fi=
le, even after applying this hotfix http://support.microsoft.com/kb/2732673=
=20
Here is the relevant code:
