Hey Sang,
When you have "not affect pictures" ON in the plugin options, it also stops regular RPG Maker screen effects from applying.
For example I have scenes that change pictures like a slide show, each with a fade in between. But the fade is never applied, nor any screen shake or flash, when a picture is already up.
Once I set the option to OFF, everything worked like normal again. I think you need to define that "ON" just removes your effect scripts, not RPG Maker ones.
