Hmmm

You should update all instances of the app. (as the old app could leave a copy of the source-file in the buffer)
Is the source file located on the same drive as is being tested?
Is there some AV that could interfere? (by scanning the file and leaving it in the buffer, if so, disable scanning on MD5 extensions or the TEST folder)

I'll have another look but there should be no reason to the file being buffered.

There will be an update one of these days as generating the checksum has been optimized. (a bit faster)
