After having edited the photos in the develop module I go back in the library module. I click on the export button in the lower left corner. Export window opens up. I choose E Mail as the Destiination for my photos. I then enter the settings for file name, file settings, image sizing and other information. I then click on the export button at the bottom of the window and instead of another window opening which used to give me the option of entering a specific email address, the screen goes blank ! Same thing happens even when I click on file and then choose export option. Please help.
