Using LR3 after Mac OS X Lion update, Merge to HDR Pro in Photoshop causes PS CS5 to crash. All available updates for both product and OS X Lion have been applied.
Problem has resolved, I didn't change anything so not sure what it was. Several attempts last night and this morning, all crashed. Just tried again for grins, worked fine, multiple times. The initial Spotlight indexing had already been completed before I tried last night, so that's not it. Weird, but fixed. Thanks for the input.
