From the looks of it Adobe are still implementing their own GUI instead of using the one provided by the underlying platform (Windows or Cocoa depending on the version)
In an app that costs as much as Photoshop does, this is inexcusable.
Just write the core code in a platform independent way, and have a small team of Windows devs and a small team of Mac devs to put an appropriate GUI on top of the core for each platform.
STOP TRYING TO USE FLASH AS A ********* GUI LIBRARY!
Have to agree with all of this.
Autodesk did the right thing with AutoCad. Which Adobe did the same.
