I am having trouble with left side panel in, library - lightroom 5. I don't seem to be able to open more than one area at a time. ie: if I open catalog and then try to open folder..catalog will close. I have also noticed that the little triangle that I click on to open and close an area is not a solid triangle but is kind of dotted. Have I done something to change the settings or something? I want to set up a new collection but I can't open both folder and collection at the sametime. HELP!
