Black axis around imported models won't go away?

Hi there,

I have imported some models of trees into my landscape design. I have altered their shape with the scale tool which brings up yellow lines around the model; and moved the model to its position with the moving tool, which brings up blue lines around the model. But after I am finished all this and click off the model, an x-y axis with black lines remains around some of them (but not all) and I don’t know what this is or how to get rid of it? Thanks!

Hi Straydog Ab,

Perhaps you could post a screenshot so we can see what you see.
