Something you said gave me a partial solution to my woes. When you mentioned working over your network I had a thought and saved by drawing locally to my workstation. This helped out considerably as I am crashing less (note: I said "less", which means I am still crashing, but less now than before). My guess is that working over the network requires more resources and/or is causing some sort of a data delay as information is being read/written over the servers (which is serving hundreds of other users at the same time). I don't know if my theory is valid and even if it is, how to bypass it right now (saving locally is all well and fine, but it requires me to be sure to park the file on the server every night, otherwise my files don't get backed up and are not available to other users ). This will become a moot point in about 3 or 4 months when we upgrade to gigabit network, but I will have to find a solution right now.
