Wierd situation that has just recently started.  While creating the slideshow, everything works fine; previews; dbl clicking the finished show etc.  Lately when I click to view show or open up the file in PTE, the preview doesn't work nor the finished show.  The cursor just blinks erratically and I need to press escape to be able to use my mouse again.  If I restart the computer, everything works properly.  Any ideas as to what's going on? Thanks in advance for any help! Travis
