just an interesting note: Lr has been running OK for awhile until I added more small 12mb raw files from the Lumix 200 last night. For some reason it went pair shape again. Seemed to battle adding key words (??). i usually add a basic one or two keys and then do some editing, sorting, deleting before getting more serious with keywords. Last night I added most keywords beforeediting, sorting, deleting. (??????)
I didn't have too much drama with some recent 5D11 raw files
