Try entering a media file by clicking on the Person Tab then clicking on the Birth, Death, etc. row which relates to the media you want to insert. Then choose the Media Tab and enter a new media file. See if that works better. Also check your media's file size. Large files seem to cause the program to hesitate or crash. Most of our media files have been reduced to a couple of hundred kilobytes. Lastly, look in your "Media" tab for file thumbnails that don't show the minature picture of your file. They may show as a symbol. These are corrupt files and should be deleted and replaced.
