Geopak Plan Graphics Error

I am trying to use the "Plan Graphics" dialog box within the Geopak Corridor Modeler tools, but I am missing some buttons. I am not sure if it is related or not, but this seems to have started happening after I installed Geopak SS3 along side SS2 (so that I can trial and learn about SS3). Other users in our office running the same version of Geopak SS2 (v...7.536) do not have any problems. They do not have SS3 installed which further makes me think it is related to that. For what it is worth, they also have a slightly different version of MicroStation than I do (v...09.357 and I have v...09.397).

Any ideas what is happening? Do I have to uninstall SS3?

Thanks,

Ken
