Tried the 1.16beta, didn't change a thing. Here is what is happening to me with Start8 1.16 and Windows 8 Blue (dual monitors):
-Takes over 1 1/2 min to get to a "desktop" after I enter my password (see below).
-Primary monitor remains gray, secondary monitor displays OK but taskbar is missing until I click on it.
Have to press left Win key to restore my desktop on the primary monitor.
-Start button no longer works with mouse. Have to use left Win key to launch it.
Hope you get this fixed sooner than later. I uninstalled it because of the instability of the start process with it installed.
Advice to others: Until you hear that this is fixed do not get the Blue Update if you love Start8!!!
