I am getting frequent crashes with version 11(4-5 times /day). Error messages vary from "run-time error, out of memory or no error message and restarting immediately. It seems that double clicking on anything( write orders, lookup diagnosis, selecting a scanned document, etc.) when in the patient's chart may cause the crash.. It only happens with my computer. The front desk states that they do not see any crashing. They however do not open the amount of sections of the patient's chart. When it happens and you restart AC, only sometimes it would ask you if you want to resurrect the note. You can imagine what happens if you do not get that option on restarting.
This version seems to be the most unstable from previous portions (almost like it wasn't ready for primetime?).Very annoying and seems to be functioning better if you frequently shut down AC multiple times a day and be patient when clicking on something and waiting.

This is my opinion, hoping for a more stable version soon.
