I get a "Blank" Ligthroom Catalog screen when I open LR4. I have to click on the wrd "Library" to get my photos to show up. What can I do to get entire Catalog to open?
Do you mean you are clicking on Library from the Module Picker (the bar across the top)? If so, what module are you in when you launch? Lightroom should launch showing you exactly what you were looking at when you last closed it. If it is not, you may need to recreate the application preferences to reset it back to default behavior.
