I'm having a problem with occasional slowing of 2 particular client computers. AC doesn't crash on these 2 computers - it just gets really slow.
I think it would be useful to know which computers have 2GB memory. I have noticed slowing on computers with 2GB (esp. on 64 bit Win 7), however when increased to 4GB, all the problems disappeared.
On two other computers, AC crashes a lot, like several times a day. AC doesn't slow down on these 2, it just stops working and closes down by itself.
It doesn't happen in any particular screen? Just random? It would help to know your networking layout. E.g. are all computers wired to a gigabit switch?
