I've just moved into platinum from the ancient X3 Producer. :)
 
I'm travelling Platinum world, it is just amazing!
 
One thing I have to ask you guys,
 
In fx rack of sonar X3, One-click the fx means just choosing that fx, and I can remove it by push delete button on my keyboard.
 
In sonar platinum, Just One-click opens the fx.
 
Is there some setting about this situation?
 
Please Give me some advice.
 
Thanks!
 
Best,
SOHN.

Thanks for upgrading to Platinum.
The new behavior is to open plugin windows via single click since it saves a click for the most common use case. To get to the menu where you can delete a plugin you now click on the dropper arrow to the right of the FX entry in the rack. You can also use the arrow keys to navigate to a plugin and press delete to remove it.
 
The behavior that is configurable is the recycle plugin windows behavior. If you prefer plugin windows to be opened independently as before you can change this in Preferences >> VST Settings.
 

Thanks Noel. I already turned off 'recycle plugin windows'.
Still getting used to platinum!
