    Lightroom slow performance causing Force Quit


      After culling/editing about 40-50 photos in both "Library" and the "Develop" modules, Lightroom slows down to the point of not working. I try to close Lightroom but it stops responding so I am forced to "Force Quit." This happens every time I use Lightroom over the last month. This happened in both Lightroom 5.5 and the earlier version. I have an IMac 2.7mHZ Intel Core i5 with 4 GB of RAM.  I have about 200,000 photos on external hard drives. Does anyone have any advice on how to fix this problem?
