some permissions on my OSX Lion accounts were having the following issues after updating to 10.7.2

It could have been caused by something else (like me screwing around with the ACL permissions on folders etc), but this was the major change at the time.

Issues included:

• windows would not save when closing. e.g. safari would revert to home screen and didn't save open tabs.
• restarting would load an old user session of open windows
• Preview and TextEdit app would crash when attempting to load them
