Been encountering same problem after d'ling certain files, particularly, avi files. Since windows explorer keeps closing, I simply return to LW shared files folder and delete the file in question there. Problem solved. I originally noticed the problem as I was unable to view a video in the default player (played in fast forward only). So I would use windows explorer shared folder to select a different media player. Cant do that now that windows explorer closes before viewing. Again, simply deleting from LW folder (if that still works) should fix problem. Still looking for a better answer myself to that windows problem.......grrr!
