Hello,
I was trying to open 2 file folders at once using windows 7. Usually I click/hold and move to right/left, somehow I did pass the monitor, and file dissappeared. Not sure how to get it back. it showed on the taskbar, but could not get it open up no matter what I do -- turn off, reset resolution, please help
