ACAD freezes when selecting blocks or xref's with certain LISP's loaded

[drubinW4ZLK]

Has anyone had ACAD freeze for 15 to 20 seconds when you click on a block or xref? I'm asking this here on the LISP forum because in trying to fix the problem I installed a newer version of ACAD (2025) without migrating any of my old settings or LISP's and it worked fine for a while. As I started to load the LISP's I use a lot to the "Startup Suite" the freezing started again. I figured that's the problem so I took all the LISP's out of the startup suite and restarted ACAD and the freezing continued. So now I installed ACAD 2022 and haven't loaded any LISP routines and it isn't freezing.

Does anyone have any ideas why this might be happening?

Have not happened to me before but you can try starting AutoCAD in safemode which does not load any add-ons and see if that makes a difference:

Also you can also try Resetting AutoCAD to see if that helps

Tried both and no luck. My fresh installs with minimal modifications are freezing now too so I don't really know if it is the LISP files that are causing it. 

Thanks for trying

Try creating a new Windows local admin account and then try AutoCAD again under this new user

Wild guess, may be a resources issue (memory usage).

A few things to try.

Put (GC)  - garbage collection at the end of those Lisp's

Check Windows startup (remove those items that you don't use all the time)

Do Disk Cleanup

Check CPU speed / performance when running Acad - see if it spikes when freezing
