I ran a plot-script with hurricane that didn't work. I closed Hurricane and AutoCAD 2012. Then i tried to open a couple of drawings in AutoCAD to see what was wrong with my script.
Suddenly my AutoCAD only allows me to open one drawing at the time. If I'm trying to open more than one drawing it asks me if I want to save my current drawing. Regardless if I press yes or no it closes my first drawing and opens the second one.
