Are you using CS4 on the Mac or Windows?
Does this happen all the time or just every now and then?
I've seen this intermittently on my Windows machine under CS4. Where when I switch between two open files the selected contents on the stage will be all rearranged in crazy ways. A quick undo should put them all back.
I've never been able to figure out what causes it. Seems to happen 2 or 3 times and then it won't happen for a week or a month.
I had never noticed a connection between copy and paste, but maybe there was. Although usually in my case I think I was copying code and not stage objects, hmmmm.....
Have you done the 10.0.2 update. I'm not sure I've had this issue since then.
Thank you both for your replies.
I am using a Mac with CS4. It is just one of those niggling little things, and I wondered if there was an obvious answer. Since there does not seem to be, I will just live with it. (need to dedicate the time to the overall project)
