For some reason when I insert a cf card into the slot in the front of my computer it opens up into a window called canon. The window display two folders DCIM and inside that there is a folder called 100 Canon. This never used to happen, it used to open up an auto play window where it asked my what I would like to do with this media. I have tried everything to get it back to the way it WAS, but nothing seems to work. I am using Windows XP.
