This is one of many acknowledged bugs that can be found in the Known Bug List here in the Report an Issue section of the forum.
It can also be downloaded as a database file from: http://www.4shared.com/file/8orL8apk/FMP_Bugs.html
We appreciate you keeping the bugs file. It would be nice if FMI kept ANY kind of tracking. And, if nothing else, they should post a link to your file if someone types BUGS in the Knowledge Base search.
FMI is still ignoring the needs of their customers in this regard. Our corporation, for one, is getting tired of it.
