I have a wierd problem on one of my main Domino mail servers. If you look at the screenshot, you will see a whole bunch of tasks that show up with a [ as a task name without the bottom right part of the bracket. Its not an available key as far as I know, so you'll have to see the screenshot to look at this. My other 4 domino servers do not have this. When looking at the console or log, there doesnt appear to be any problems.
I am running a 64 bit - Win 2003 Server and this is Domino 8.5.
Any help is appreciated.
