I have an image of an Eagle sitting on a branch on a cloudy day. The eye is a bit dark because of the extended forehead. Whenever I select the Adjustment Brush to lighten the eye a bit Lightroom 4.3 quits. I have had no issues with Lightroom 3 and forward until after I upgraded to 4.3. Has anyone else had this issue and if so is there a fix? Mac OS X 10.7.3
