Hey everyone, you all have been really helpful on my issues, so thank you! I have another odd thing happening that maybe someone can help with.
I wrote a lisp that the user selects 2 points, and the lisp inserts, rotates and flips various dynamic blocks and it works great... On my home computer. However, when I use the lisp at work, the program pauses indefinitely after the user clicks the 2 points like it's waiting on additional input. The points selected are either intersections, endpoints, or midpoints of lines or other dynamic blocks, and when the program has these strange pauses, the line or the block that I'm snapping to is highlighted. Nothing happens at all, but if I roll the mouse wheel to zoom in or out, the lisp breaks out of its funk and finishes the lisp routine properly. As you can imagine, this is really annoying. Hopefully, this is just an easy setvar to change, and not an "uninstall/reinstall" type of deal. Thanks again!
