I placed the following line of code in my acad.lsp start up file (vl-vbarun "[path]") when I have autocad reading acad.lsp only when autocad is opened, the line runs fine. If I have autocad set to run acad.lsp everytime a drawing is opened it seems to get stuck on this line and I have to shut down autocad. Why would this be happening?!? I'm using AutoCAD 2000i Thank you very much, Edward
