I see an issue when SIB+ is used together with Win8.1's built-in family safety feature. I have a child account set up with time limits, SIB+ active and set to go to the desktop on login. In many cases when family safety takes over the screen but before the desktop is shown (such as after login or resume when you need permission for more time) once you get to the desktop all the icons are missing. There are what appears to be 1 or 2 minimized windows instead and double clicking on one gives you the icons back. I attached a portion of a screen shot. It is a bit inconsistent when this happens, but it never occurs if SIB+ is disabled for that account. I think the most consistent way to recreate it is to let the users time expire, put the PC to sleep, then wake it and add more time. If you need any more info or help to get this fixed I'll be happy to assist.
