LastPass is IMHO a killer app.
The only issue that I have is that LastPass App for Mac OSX status menu item, after some period of time stops functioning.
The quick description is that the menu drop down from the status menu icon stops working after undetermined period of time.
The long description:
Start laspass App. The status menu is grey with white dots. Click and it is white with blue bots and blue border and menu.
Use mac as normal, locking it whilst away from screen. Nothing in particular found that causes the problem.
The icon has gone white with blue dots and blue border. Clicking it does not get the menu.
Launchpad, start lastpass appears in tray, right click, quit, launch pad, start lastpass usually fixes status menu
Launchpad, start lastpass appears in tray, open, apple > force quit > lasspass, launch pad, start lastpass always fixes status menu (so far).
