"terrian window" next to cursor

[lgswe]

I brought an X5 plan into X6 to work on some revisions and I have the "terrian icon" (I hope that's the correct term) showing next to the cursor. I'm not sure why it's there since it wasn't there when the plan was open in X5 and now I'm in the "Default Config." in X6. I know (or I think) there's a way to turn this on and off, but for the life of me I can't remember how or can I find it in the help. I'm sure this is due to not knowing where to look or what to ask. Before posting this thread I closed X6, then reopened it along with the same plan and the "terrian icon" is no longer next to the cursor----go figure. I think someone is putting something extra in my coffee! Anyway, I guess I'm still asking the question. How do you go about turning this icon (or for that matter ANY ICON) on and off next to the cursor?
