Marcus stared at the screen. His coffee had gone cold two hours ago.

One problem remained: the docking system's theme. In the old version, DockContainerItem used a custom paint handler that no longer existed. The form would render—but with weird black flickering on the tabs.

"This suite was written when Windows Vista was cool," Marcus muttered.

He added a new SuperTabControl to a test form. Set ThemeStyle = "Office2019Colorful" . The flicker vanished.

By 4 PM, the solution compiled. The main dashboard loaded, ribbons intact, docking windows snapping into place.

The culprit? .
