Software Deployment

I have created an SMS package for the Live Meeting 2007 add in (included with it is a transform with the customizations I want to make). I've done a test deployment to 5 development systems. Out of these 5 systems, 3 have given me a message in event viewer that a reboot is pending to compelte the operation. Looking back through the .mst, the REBOOT property is set to ReallySuppress. I've noticed some entries in the control and dialog tables that pertain to a reboot, but I would think a dialog would only be tied into the UI sequence. Not to mention, I see no conditions tied into these dialogs. I've even run it manually and the installation completes without a reboot needed. Anyone out there work with this product yet? If so let me know if you've run into this issue. Thanks.
