Hello,

Thanks for attached sample. I saw the mentioned behavior, but this behavior is expected because Minimize, Maximize and Close buttons have there different states:

- Normal state

- HotTrack state - when the mouse is hoverover the button, but the button is not Press

- Pressed state - this is the state when the button is pressed. This is the moment when you see the changes for a short time

The mentioned behavior is by default and if you want to change it, you have few possible options. Please note that all options used UltraFormManager.

Option 1 - Using UltraFormManager with AppStyle - I made small sample for you using this approach. I made modifications in the AppStyle, so each button (Minimize, Maximize and Close) have different HotTrack appearance (for example: green, red, yellow). Also I set Blue and Pink color when the buttons are in Pressed state. By this way you are able to change the default appearance of your application

Option 2 - Using UltraFormManager without AppStyle - By this way you could change the HotTrack and Pressed state using directly the properties of your UltraFormManager

Option 3 - Using only UltraFormManager and DrawFilter - Maybe this is the most complicated scenario, because you should create additional class.

Please take a look at the attached sample and video file for more details. If you watch the video carefully you will see the HotTrack and Pressed states of the buttons 

Let me know if you have any questions.

Regards
