General Description: When I select "check floorplan", the message window is blank, but errors are indicated. The single line string for each error is not displayed, but a place holder is still present in the window.
The errors indicate that an area group is not big enough for the selected items. If you click on the upper-right corner of the message window, in the white box, the tools will highlight the suspect area group. For every error, there will be a blank line in the white area of the message box. If you change the size of the area groups simply by increasing them, you may then perform the "check floorplan" process.
This issue will be fixed the in the 5.1i software, which is scheduled to be released in September, 2002.
