What steps will reproduce the problem?
1. In Windows XP Pro (3,5 Gb RAM) run scan 17 sheets in scanner with ADF.
2. At 15 or 16 page pops up an error: Out of memory (-4500)

What version of the product are you using? On what operating system?
TwainDotNet 1.0 at 12-03-2011
Windows XP Pro x86

Please provide any additional information below.
Start scanning code:
try
{
 if (SourceUserSelected.IsChecked == true)
 {
  _twain.SelectSource(ManualSource.SelectedItem.ToString());
 }
 _twain.StartScanning(_settings);
}
catch (TwainException ex)
{
 MessageBox.Show(ex.Message, "Scanner error"); <-- The error occurs here
}

Processing of scanned page:
_twain = new Twain(new WpfWindowMessageHook(this));
_twain.TransferImage += delegate(Object sender, TransferImageEventArgs args)
{
 if (args.Image != null)
 {
  //Resize scanned image to A4
  Bitmap image = Functions.ResizeToPdfA4(args.Image);
  ScannedPage scannedPage = new ScannedPage(image);
  _pages.Add(scannedPage);
 }
};

At each stage of the procedure is performed - GC.Collect();
