I only installed AC 20 a couple of weeks ago, and the more I work with it the worst the problem gets.
I find more and more objects plagued by this behaviour and am unable to do my work properly. Very frustrating to say the least.
Hopefully this can be fixed by a patch in the very near future.
Cheers
