**This is misleading. Of the four types of machines we have available here, 
the one Valery suggested we try was this one. It appears to be true that 
some machines will not even exhibit this problem while others might be 
affected even more severely.

I would also like to inform the group that Valery's response was 
interested, quick, and helpful.
