Why must a server be running for the GlowBuffer to function?

I am working on a dialog where objects in a GuiObjectView control have a glow buffer applied to them. However, when I push this dialog, the GlowBuffer does not display unless I have a mission loaded... what gives? I've been through the code and it doesn't seem to be doing anything special for the glowbuffer when you load a mission... what am I missing here?
