I'm not sure whether this applied to the 7.450 version, but after the upgrade to 7.460 I noticed a few inconsistencies in the dashboard formatting. Specifically...
HTTP Proxy stats include a space where I would expect a comma (e.g. "8 043" instead of "8,043"). By contrast, the Intrusion Prevention stats don't include any formatting (e.g. "8043"). This seems to be the case on some other pages too, such as the "Network Statistics - Today" page off the main Network link - it shows "576 247" for a packet count, instead of "576,247".
Most counts include a space after the delimiting commas, but the AntiVirus and AntiSpam counts do not (e.g. "HTTP,FTP,SMTP,POP3" instead of "HTTP, FTP, SMTP, POP3").
