1.2.0 seems to have broken the banner timers.
I have hide set to 8 and display set to 3600 and it still pops up every 30 seconds and stays for I guess 30 seconds.
I can't actually tell how long it stays as the display and hide is the same default amount.
(maybe set the default timers to 10 for hide and 60 for display or something like that)
Also, if I unload the plugin while the banner is displayed, the banner is not destroyed but stays forever (until X is clicked), and on reload, a new banner is displayed on top.
