Web Forms :: Image Copy Doesn't Work On Windows Server 2008 With IIS 7.0

I have a small function that is in a STA thread. It's purpose is to copy the selected image in word document to clipboard and then save it to a location on the hard drive. Here is the code that works fine on XP and Windows server 2003.

protected static void CopyInlineShapeFromClipbord()
{
string imageFileName = string.Empty;
_oWordApplication.Selection.Copy();
Computer computer = new Computer();
if (computer.Clipboard.GetDataObject() != null)
{
System.Windows.Forms.IDataObject data = computer.Clipboard.GetDataObject();
if (data.GetDataPresent(DataFormats.Bitmap))
{
Image image = (System.Drawing.Image)data.GetData(
DataFormats.Bitmap, true);
imageFileName = _imageUrl + ".gif";
image.Save(imageFileName, ImageFormat.Gif);
_imageUrl = imageFileName;
}
}
}

It does not work on Windows server 2008 on IIS 7.0 Is there some known WP Identity issues or any other kind of security issues in cross process memory sharing?
