I have a Lisp program that was working fine until recently. Now, it is failing on a (command "Boundary" Point). It fails to create the boundary, which is created to calculate the area of that region and is deleted after. There are other boundaries created prior to this line and they all work fine. Could someone give a hint as to what to look for, I have done most things I could think off and still haven't been able to fix it. Is there any that could affect the performance of the boundary command? I am using Acad2004 on WindowsXp pro, SPack 2. I would really appreciate any suggestions. TIA.
