Grey around the room?

[vexxice]

I have imported many backgrounds into my game, but everytime I import a background, A grey area appears around bottom and right sides of the room. It doesn't appear in the game, but I'm wondering if I should be concerned.

I guess what you describe is just an unused space on the editor window, so you shouldn't bother

(I have same all the times)

Thanks, I thought maybe my ags was functioning improperly.
Wait! I just noticed when I put my mouse in this grey area the x value becomes "?". This still concerns me.

As Crimson Wizard said: It's unused space. Unused space cannot have a coordinate since it's not part of the room. Everyone has this when importing a room. It's normal.
