Victoria,

Thank you for your response. It gives me hope!

I really appreciate your offer to help. I have not worked through a forum before but I am assuming you are an Adobe employee, right? It would not seem fair to ask for this much help from someone who was not an Adobe employee.

In any case I should try your first suggestion of letting LR run. I know I have let it run about an hour and I may have tried over night. At what point would you give up on that approach?

In answer to your question of size I just went to check it out and found it is 145 MB. I have lots of photos marked with 1 star that I plan to delete so I would really like to get the rating functional.

I also noticed eight sets of files that say:

Temporary Import Data - #.db and

Temporary Import Data - #.db-journal

I am wondering if they have anything to do with the problem?

This is a "Yes", I would like help.

Thank you!

Larry

Thank you! I really appreciate your help. I will start on this at lunch time, since I have to work at the moment.

Victoria,

I moved all of the temporary files out of the way and tried again with no improvement as expected.

I found and moved the files "com.adobe.Lightroom4.plist"  and  "com.adobe.Lightroom3.plist" to a different folder with no improvement. I left behind the associated lock files, Should I have moved them too?

After moving the preferences files it locked up as soon as I selected Rated under Filter: (lower right) in the Develop screen.

Previously after a lock up and a Force Quit I would come into Develop and click once on one of the 5 stars that would filter photos > or = to X number of stars. The first selection would work but as soon as I made a second selection it would lock up. It also would lock up when I attempted to add a star to a photo using the numbers (as short cuts) on the keyboard. Curiously if I set the stars associated to a photo by using the mousepad and arrow it did not cause the problem. (Just checked and this still works.)

I have just over 14000 photos all of which are raw files in the 20-25MB size range.

Thanks again.

Larry

Victoria,

When I go into the app the  drop down box titled "Filter:" in the develop mode is set on "Filter No" so I cannot filter at all until I make a selection and doing so causes the issue.

I just tried creating a new catalog and it appears that locked it up as well. Although it has only run for a few minutes, so I will go plug it in to the wall and let it run for awhile.

I just wondered if I had used up all the space on the hard drive. I have used 593 GB out of 749 GB. Could that be part of the the issue?

Larry

Victoria,

I pressed the word filet and got the options, set three flags and tried to filter on flag. It resulted in the same lockup. Also the apparent lockup when I tried to start a new catalog was really a lock up, even many hours later.

Thanks again.

Larry
