A buffer error occurs when the output buffer is full or the input buffer 
is empty. As the output buffer is set on each read operation it has to be 
the input buffer.

Put a:

writeln(Fstream.avail_in);

... at the end of the reset procedure. If it happens to be non-zero, we 
have found the problem.
