I have created a slideshow with 399 photos, which includes a few video clips. The slideshow has got to the stage that everytime I try to do anything, eg create a text overlay or delete a slide the app goes off into the ether. The mouse pointer either disappears althogether or is replaced with a blue rotating circle. A message "Not responding" also appears immediately after the file name on the top row of the window.
Is the computer being slow to respond? Am I being too impatient?
Any suggestions??
