The following problem has been brought to my attention. Any help would be greatly appreciated.

When replying to an email the received message isn't quoted. When replying to a different message from the same sender with similar content i.e. text only, the received message is quoted. The same happens when forwarding mail. If all the text in the problem email is highlighted it then includes the text in the reply. This problem occurs for more than one user on the same machine. Both users have the same problem with the same emails on a different machine. Both machines are Mac (iMac and MacBook).

System info:
iMac 10.1
Mac OS X 10.6.4
Groupwise version 8.0.1 1/8/2010 Build nr 89145.9819
Java Run Time 1.6.0_20-B02-279-10M3065
