While testing the new CVS today, my 600 locked up occasionally with the 
"SYSTEM ERROR2252" message displayed. One time ( that I noticed) ptal-hp 
returned this message: "ptalChannelRead returns 0! Broken pipe". All of the 
lockups ( 3 times today ) happened while scanning at -res 150. That may be 
because I made more scan attempts at that resolution. In total I made about 
35 scans, at least 5 at each resolution that the 600 supports.
