Panorama, Sint Marteen

I've been here several times. I only once created this type of pano. I've tried this several more times with assorted places around the house and have found that PSE and Lightroom seems to be having trouble stitching them together and not varying the exposure from frame to frame. I've even used photos that were exposed on manual with non of the setting changing. Maybe the whitebalance, I'll have to check that.
