Hello,
Sorry to hear you are having issues. I believe this is standard behavior for Windows 7 Startpanel. When there is a program in the left Start panel, with last open file history or Function/task choice, the list will show up when you hover over its icon. I believe there is no option within Start11 configuration windows to disable it. Not sure if there is a regedit hack to manually remove it. Someone might come along and give a tip if it is known.
Thank you.
