I've been having a few problems with my AutoCAD setup recently where random system variables are changing value. For example, autosave being turned off, autosnap marker changing color, etc. I also noticed that every time I open a drawing an 'acad.lsp' file is created in the same folder from which I opened the drawing. I have attached a sample of the lisp file it creates.
I do have an acad.lsp file in my support directory which loads a few commands ( so it's about 10 lines long) and I have my system set up to load it into each new drawing. But recently it doesn't get loaded, so I'm assuming it's picking up these alternative acad.lsp files and ignoring the one I want loaded.
I'm not so much concerned about the system variables changing because it hasn't happened for a week but I'm getting tired of deleting these acad.lsp files everywhere they pop up.
Any ideas out there what might be causing this to happen? It almost seems like some kind of virus which isn't a big problem but could have been.
Thanks.
