purple square?

According to the documentation, this means no report for more than 24 hours. But this is the BBDISPLAY server, local messages coming from bigbrother. When I click the button for cpu, disk or http and display the screen for every instance, everything is ok and shows the actual date/time.

Hobbit is 4.0.3, kernel 2.6.8, Mandriva 10.1.

Any hints?

Yours hjb
