Try my own block checker :
http://msn.home.dyndns.org
It's very accurate, but i need a server to host it.. So sometimes it may be down. When down, i put notifications on the forum, and anyway your list can be saved, and you always can check status with OSI.
My checker shows display names, and you can check several accounts at the same time. And more faster than others because coded in python
Usually up 75% of time, but will be down this week end, cause i go fishing, so try it on monday
Fishing problems will be solved as soon as i find a server to host my little app !
