R2005, I got my reactors working and made them persistant for a block in a certain drawing. Only trouble is, when I close the drawing and re-open it, the reactors are there and function like they should but the lisps that the call are not loaded in the newly opended drawing. Is there a way I can load these lisps in just this one drawing? Can I do it with a reactor? Or do I need to load the lisps in all drawings on startup? TIA Bill
