All of the DMG Plugs (Equilibrium, Essence, Compassion, Limitless) are resizable.
Wavelab 9.0.35 has a problem recalling GUI sizes and it will show only a part of the GUI, the whole GUI is not accessible anymore. As a result all settings are lost as they are not tweakable anymore. The only solution is to reinstantiate the Plugin and do the work again.
This happens in the MASTER SECTION (DMG Essence, Compassion, Limitless) when recalling presets.
This happens in the CLIP FX Section (with DMG Compassion) sometimes only when switching between various plugins in the plugin-chain-window.
