I am having an issue when saving the first group 4 tiff that I open in
the viewer. The TIFF tag StripByteCounts (#279) is being set to 1 when
I save the image. This only happens on the first image. If I open a
second image and save the file, it is saved correctly. Another
interesting piece of info with this problem is that is works everytime
if I am running my application in the IDE. I believe in my testing, if I change the format to be just 'ccit' the save worked correctly.

I am attaching a simple example program so you can see if I am doing
something wrong in code. Included in the zip is a TIFF file that is not working correctly.

Thanks in advance for your help.

You are right. The code causes different values to be written to the
StripByteCounts tag if it is executed inside the IDE and outside it.
However, both values are incorrect. To get it to write the correct
value, the stream must be seekable. When I changed the "new FileStream"
line to use System.IO.FileAccess.ReadWrite instead of FileAccess.Write, the problem seems to be solved.
