after upgrading to LR 4.2 I run in the following Problem.

LR runs with an acceptable speed as long as I stay in LR.
There are no known problems with jpg files.

As soon as I use "Edit in PS CS6" (Canon Raw Files CR2) it takes about 30s till photoshop is showing the picture.
Then I leave PS without having done anything LR still runs fine until I close LR.

The next time I start LR It stucks for about 6-10 Minutes, after that time everything seems to be OK till I "edit in Photoshop" the the scenario repeats.

Going back to LR4.1 everything is OK.

This problem is reproduceable with 4.2.

Exporting the catalog and importing into a fresh and empty catalog is of no success.

There are about 100000 pictures in the catalog.

For testing purpose I exported only 1 picture in a new catalog. When I open this catalog and do a "edit in CS6" the next start of LR is delayed for about 10 Minutes. (Stuck with rotating cursor)

System is
W7 64-Bit
4 Core 3,4Ghz
16GB Mem

For testing I use a catalog with only 1 picture.

Any Ideas?

More Information on this topic.

I deinstalled LR 4.2 as well as PS CS6

Reinstalled both products and did not apply the Adobe patches!
Everthing is fine.

Applied all Patches thru "Ckeck for updates" except Camera Raw.
Everything is fine

Applied Camera Raw update (7.2)

Ouch.... same Scenario

What about the Adobe Camera Raw cache - Preferences, File Handling. Purge it, increase its size, verify its location is on a fast drive.

Also go through

thanks for your reply, but all the steps in the mentioned doc had been checked.

If definitely runs fine til I apply the CR7.2 Update to Photoshop.

By the way everything runs on Sata-3 SSD Drive
