Flatten button in the tool properties is missing

The Flatten button in the tool properties is missing for the select tool.
I may have accidentally changed some settings…
In the video tutorial video 9 there are several buttons in the tool properties that i do not have…
What can i do to get the buttons back?

the video is the video titled Selecting Drawing Objects

Wow, I’ve never heard of this one before!

Probably the best thing to try is trashing your preferences. Close the application. Then look for the preferences folder, which is in the following location:

Mac: /Users/YOUR_USER/Library/Preferences/Toon Boom Animation/YOUR_PRODUCT

Win: C:\Users\YOUR_USER\AppData\Roaming\Toon Boom Animation\YOUR_PRODUCT

Now simply trash that whole YOUR_PRODUCT folder (it’ll be called Toon Boom Animate or Toon Boom Animate Pro depending on what you’re using). Then try relaunching the application.

If that doesn’t solve the issue, try reinstalling. And if that doesn’t help, contact support@toonboom.com
