I am getting an error on running G4P V4.3.8.
> The GWindowAWT class cannot find this method
> public void winMouse(PApplet applet, GWinData windata, MouseEvent ouseevent) { /\* code \*/ }

The app runs, putting up a main animation window and a subsidiary window of G4P controls. Everything works, including numerous event handlers, but the mouse events and key events in the control window can’t be caught.
I have tried running similar handlers in a much small app–there it all works. The handlers for key and mouse events are present and properly formatted, and I checked the file for bogus characters. There were none.
Here’s a typical handler:
```auto
synchronized public void winKey(PApplet appc, GWinData data, KeyEvent kevent) {
println("ControlWindow - key event " + millis());
}
```
At this point, I’d welcome suggestions.

Posted the problem and then I solved it. Typical.
Because I had also imported `java.awt.event.*` to my app, the signature for the `winKey` method was misconstrued by the JRE (or so I surmise). By explicitly citing the type:
```auto
synchronized public void winKey(PApplet appc, GWinData data, processing.event.KeyEvent kevent) {
println("ControlWindow - key event " + millis());
}
```
Problem solved.
