What are the system specs as far as CPU and speed, and what type of raw files are in the folder you are visiting?  The only way I know that it can lock up is if one of the files in the folder is corrupted to the point that the error is not recoverable.

Hi Doug,
I have a  P4 3.6 GHz machine with 2GB dual core memory and I do not have any problems with switching folders mid thumb/cache building. I just wait a few seconds and QU swops over to the new folder.
With old single CPU machines like ours, thumb/cache building is relatively slow, for me, 9.7 secs per 350D CR2 image. On my dual CPU laptop, 2GHz, it's 6 secs per image.

Despite that, I like the fact that other operations with raw, screen view, editor, slide show, printing etc., are so much faster with the raw cache being there. I now just time-manage the caching process by choosing when I allow it to be done and then do something else.

Doug,
Have been following you and Terry discussing the "old" machine.
That caused me to try Ultimate on my old machines.
I have a P IV running a 3.20 gig clock speed with 4 gigs of Ram.
No crashes, but it is running W7 32 bit.

I have an older one which still has XP on it. We never even turn that on. But I tried it anyway, and installed Ultimate.
Slower, but no crashes.

My own computer is a Quad core, and Ultimate makes use of the quad when building cache files and thumbs, and that is slick.

My point is you mentioned turning off cache file building and still crashing.
That leads me to believe you have a system failure or conflict. With cache of files and creating the cache turned off, you are essentially running Studio with the current versions.
Ultimate should be running as if it was Studio.
Have a look around!  Uninstall, reinstall, turn off the anti virus when reinstalling. Try a few things!

I am running on a Mac / Fusion VM Windows XP  Ultimate is running slow compared with the  Studio Edition.

Somehow, I think the point has been obscured during the discussion of the slow cache and thumb building.
BTW Mike is working on a speedier method of getting the cache built.

The point that is missing, that seems to be crucial, is that the quality thumbs and the cached Raw files are created **ONCE**.
Right now, if one were to take a a folder with 200 Raw images and using an old slow processor, waited the 10 minutes it took to create the cached files, Ultimate would work the raw images over in Lightning Raw mode.
After that build time, Ultimate would open your folder instantly, allow you to zap through your work on the images, and print at higher speed, and enjoy the new technology.

It's even better than having to sit and let your car engine warm up on a frosty morning in Chicago so you can defrost the windshield. :-)
You can see the point! The benefit of the heater and defroster needs the wait time for the engine to heat.

At least in Ultimate, you find that once through a folder, it is a done deal.
If you come home after a shoot of your grand daughter in a  school play, (where she played a tree in the forest), and you sit down at ultimate, yes, a new folder, and you might wait for the new shots to cache.

Just some thoughts from Fred!
