I checked out some styles using visualstatemanager.
Using WPF Themes I checked out some of the styles.
There are styles where thumbs have a mouse over animation. And there are some which do not have it.
A closer inspection showed that styles where the thumbs have animation are "trigger based".
Or opposite: all styles using VSM (like RainierOrange or Daves-Glossy for an example) do not have animation on thumbs.
Any idea why the thumb states do not work?
Thanks in advance
