Novell GroupWise 8
GroupWise 7 allows a maximum of two columns of panels. GroupWise 8 allows the definition of additional columns of panels. If three or more columns of panels are defined in GroupWise 8, then an earlier GroupWise client is run, the panels do not display correctly and will need to be adjusted when returning to the later GroupWise 8 client.
Displaying panels with varying monitor configuration, such as standard vs. wide-screen monitors, single vs. dual-monitor setups, can also result in altered panel display.
