The Google Crawler has caused a couple of problems on different machines of mine. On one it kept triggering the Virus Checker (I suspect because it was trying to scan the Quarantine directory). On my other machine it keeps throwing up 'Error 226...' can't remeber the rest. It appears after an hour or so of running the Crawler. Appears some underlying conflict is going on between the Crawler and someother program - maybe the virus checker again?
