po odinstalowaniu np. gdy ktoś miał CS2 to trzeba będzie go przeinstalować...
i parę innych drobiazgów z Acrobatem, jakby ktoś miał problem z linkiem, to poniżej treść tego faq'a:
KNOWN ISSUES:
Known issues for the Photoshop CS3 beta include the following:

* Uninstalling CS3 removes the photoshop-9.jsx file and breaks CS2 Photoshop/Bridge interactions
Workaround: Re-install CS2

* The Adobe Media Gallery (available in the File > Automate menu) is non-operational in the Photoshop CS3 Beta.
Workaround:
1) Move the CS2 Presets from Adobe Photoshop CS2 > Presets > Web Photo Gallery to Adobe Photoshop CS3 > Presets
2) Move the WebContactSheetII.plugin from Adobe Photoshop CS2 > Plug-Ins > Adobe Photoshop Only > Automate to Adobe Photoshop CS3 > Plug-Ins > Automate
3) (Intel-based Macs) Select the Photoshop CS3 app and do Get Info on it and select "Open using Rosetta"
4) Launch Photoshop and choose Web Photo Gallery from the File > Automate menu

*CS2 version of Bridge/Photoshop launching CS3 versions - Workaround:
1) Quit all versions of Photoshop and Bridge
2) Mac: Delete the /Library/Application Support/Adobe/Launch/photoshop/10.0/ folder on your Desktop
Win: Delete the C:\Program Files\Common Files\Adobe\Launch\photoshop\10.0 folder on your Desktop
3) Mac: Delete the /Library/Application Support/Adobe/Launch/bridge/2.0/ folder on your Desktop
Win: Delete the C:\Program Files\Common Files\Adobe\Launch\bridge\2.0 folder on your Desktop

* Printing to non-default page sizes (Windows Only):
1. File > Print > check on scale to fit
2. Page setup > Select your paper size > Ok
3. Toggle the orientation buttons to force scale to fit to reflect the new paper size. After scale to fit reflects the proper size for your paper you can uncheck it at this point if needed.
4. Toggle centered checkbox on and off if you want the final output centered.
5. Print > Select preferences > set your page setup again to match the settings you selected in step 2 page setup
6. Print

* Fixed height palettes turns blank when dragged to the top of a second monitor
* Large cursors are not displayed on Intel-based Macs.
* The Pattern Maker plug-in is not available on Intel-based Macs
* Uninstall causes Acrobat 7 Pro and Reader to be automatically reconfigured on Windows XP.
* Interpolation on image resize is not working correctly.
* Certain plug-Ins are not being loaded on Intel-based Macs (AltiVec, PPCCore, Embed and Read Watermark).
* Camera Raw is not yet scriptable.
* Photoshop may crash on quit when running on a developer seed of Mac OS X 10.5 "Leopard."
* Non-Photoshop Open EXR files fail to open in Photoshop CS3.
* PDF settings are not included. If you do not have Acrobat 8, you will not be able to save out as PDFx.
* The Adobe Media Gallery (available in the File > Automate menu) is non-operational in the Photoshop CS3 Beta.
* Unable to open a CMYK JPEG or images larger than 10,000 pixels per side if "Prefer ACR for JPEG" preference is checked.
* Recovery and fill light sliders don't respond immediately on first use. If unable to open more then one JPEG on the Mac the workaround is to check the preference option to "Prefer ACR for JPEG."
* Thumbnails don't always update in Bridge after editing raw file in PS ACR.
* TWAINBridge preventing Mac installer from working (solution: use Activity Monitor to quit that process)
* MacTel platform cannot read BMP format files
* Camera Raw dialog box cut-off at 1024x768 monitor resolution

a tak się ciekawie zapowiadało... Mam nadzieję, że do wersji finalnej zdołają to wszystko poprawić.
