I wrote some code to control my mouse cursor and mouse clicks.  It works great I can launch apps, type select windows, etc

The problem is with the onscreen keyboard in windows 8.  When I use the robot mouse to click on the title bar of the onscreen keyboard it makes the robot mouse freeze up... The USB real mouse still works and using it to click on the keyboard will bring the robot mouse back into action.  This seems to only happen with the onscreen keyboard.  Clicking on the title bar in other windows does not cause problems.... Does this sound like a windows glitch or is there a workaround?
