How to keep Preview from crashing in Lion?

Question

I'm really frustrated with Lion on many counts, but today it has stopped my workflow completely.
I'm doing simple crop, resize in Preview.
Because of the idiotic elimination of "Save As" and the default change of JPG to PNG, I do this:
1. Open original jpg.
2. Duplicate (feel frustration at no "Save As"....wonder why Apple did such a stupid thing)
3. Open Adjust size.
4.  Set size to standard inches, in this case "8 inches" from appoximately 50 inches in jpg.
5. Set dpi to 200 from default 350.
6. Try Export (feel frustration at no "Save As...wonder why Apple did such a stupid thing)
7. Crash.
Do 1-6
Crash
And so on.......
I am using brand new $2400 iMac 27 with completely stock software and all current upgrades.
Any insight?
Does going back to Snow Leopard really work?
(.....when store opens, going to buy Adobe Photoshop Elements.......and will replace Aperture with Lightroom, and will buy Premiere......because may need to migrate away from my 8....hear that Apple?......eight Apple computers)

Answer 1

Apple does not "hear" here.   This is a user to user forum.   Call Apple Support by phone if you want to communicate with them, or post to http://www.apple.com/feedback/ if you just want them to know what you think about certain products, or sign up for a free online developer account http://developer.apple.com/ and submit bug reports to http://bugreporter.apple.com/ if you have a detailed reproducible bug with the operating system.
Have you run the hardware test that came with the Mac?  See this link.
If you have a brand new Mac, it likely can't be downgraded to Snow Leopard.  See what I have to say on the Snow Leopard tip at its bottom.  If it is over 2 weeks old, you are beyond most store's return/exchange policy, but you should check with the store you bought at, if it is withing that range.    If it is outside that range, but less than a year old, you can buy AppleCare, for both hardware and software coverage within 3 years of date of purchase for anything that is not an accident or user caused, to deal with Apple hardware and software.  Otherwise it is first 90 days for software and phone, and first year for hardware as far as free coverage.
Define "crash?"  What do you see happen on screen?  Is there a four language screen saying you must restart your machine?  Do you just see a spinning cursor that is rainbow colored?  Have you tried the command-option-escape if it is the spinning cursor to see if you can force quit the application?    Do you see text with black background come across your screen?   Or do you just see applications quit on their own and it says: "this application has unexpectedly quit, other applications are not affected, report to Apple?"
