Hello guys, I have very strange problem, a portions of my code works excellent on Windows 7 and Windows Vista, but on Windows XP I got 'Parameter is not valid' exception. The function that throws the exception is this:

Private Function CropPattern(ByVal intCrpX As Integer, ByVal intCrpY As Integer, ByVal intCrpW As Integer, ByVal intCrpH As Integer, _
                               ByVal bmpSource As Bitmap) As Bitmap
       Dim bmpCropBitmap1 As Bitmap
       Dim rect As Rectangle = New Rectangle(intCrpX, intCrpY, intCrpW, intCrpH)
       bmpCropBitmap1 = New Bitmap(intCrpW, intCrpH)
       Dim g As Graphics = Graphics.FromImage(bmpCropBitmap1)

       g.InterpolationMode = Drawing2D.InterpolationMode.HighQualityBicubic
       g.PixelOffsetMode = Drawing2D.PixelOffsetMode.HighQuality
       g.CompositingQuality = Drawing2D.CompositingQuality.HighQuality
       g.DrawImage(bmpSource, 0, 0, rect, GraphicsUnit.Pixel)
       g.Dispose()
       Return bmpCropBitmap1
   End Function

Does anyone know what the hell is going on? I tested my program(which is 32 bit executable) on two windows xp PCs and there is the same problem on the both of them. Both XP machines have the latest .NET Framework .
Thank you in advance.
