I finally figure out why my Notes Client would be in a hung state every time I return to my MAC laptop after a few hours away. Generally every morning.
I have my MAC setup Via Security Menu to logout of my account after 1 hour of inactivity.
Notes Client would not shutdown or could not be close by the Mac Logout process per a pop message on the desktop. So the Notes Client is left in a state of not being usable half shutdown but I could not close it normally.
I had to force quite Notes via Mac’s Force Quite option. Then restart Notes.
I turned off the auto logout feature under Security Mac System Prefences and this morning Notes was usable.
I would suggest someone at IBM look at this setting on Mac Security feature and test.
thanks
