FMS 4 log permissions defaults

We had an issue today with a new installation of FMS4, where we have developers in the group "fms" which allows them to view logs.   It turns out, FMS is creating logs in mode 0666, but it's also applying those permissions to the *directory* which prevents our model from working.   I added the g+x flag to the directories and it worked.  From Server.xml:

                <!-- This key controls who has read/write access to the shared object   -->

                <!-- files and stream files in the server. The Mask is used by umask    -->

                <!-- to set file creation mask.  By default, the mask is set to 017     -->

                <!-- and the files are created with permission 0666.                    -->

                <!-- 0666 & ~017 = 0660 = r w - r w - - - -, that means the owner of    -->

                <!-- the server and all the users belonging to the same group as the    -->

                <!-- owner will have read/write access to the files. This mask must be  -->

                <!-- a 3 digit octal format                                             -->

                <!-- This config node is for unix only.                                 -->

                <Mask>017</Mask>

Is there a way to get it not to apply 0666 to the directories?

Thanks.
