I would have said yes but reading your question again I see we are talking at crossed -purposes.
'Actions' are a recording of your workflow and have their own Panel....this is what I asked you to check earlier.
I now see that in fact you are not referring to 'Actions' at all and are in fact just referring to normal basic use of PS.
It was just an unfortunate choice of words to use but I see what you mean now.
Your problem could be any one of many things and without knowing a lot more about the system you are using, file size, plugins loaded, etc etc its impossible to say exactly what is going on.
It sounds like you are on the limit for RAM usage by PS....have you changed the RAM allocation for PS?
As you are having the same problem with two different versions of PS it sounds more like a 'system' limitation than a PS error.
Post more details about your system specs, the file size your are working on, and, if you can, how much RAM PS is using at the time the problems occur.
The more info you can supply the better suggestions you'll get.
Regards.
MrTom.
