I think the problem may well be the number of monitors.
There is a known issue in 0.9 if you have > 2 monitors and have the option in Start11 turned on (it is on by default) to apply a custom start button.
As a workaround, turn off multiple monitor taskbars in Windows settings, install Start11 0.9 and in settings turn off the custom start button option. You can now set your multiple monitor taskbar back on and you should be fine.
Hopefully this addresses the issue for you for now.
We have an update this week which resolves the issue entirely.
