small bug in SQL server 2005 developer edition with SP 2

Recently SQL server 2008 also release but SQL server 2005 I notice there has small bug but it’s not the big issue, but SQL server QA team need to find out those things. This error I notice SQL server Developer edition when you create a backup database using graphical view (Not the T-SQL) after finish database backup it show Executing (0 %) I see this error twice normally I’m taking backups 5 or 6 time per day. And I was install SQL server 2005 developer edition with SP 2,
