By RSATom:

I think we are talking about different things:
if (window->window == curr_window.window) {//this mean that window was not changed.
/* resize / move notification */
+ p_plugin->setWindow(*window);//then why we need set again something that don't changed?
p_plugin->resize_windows();
} else {

or you mean that NPWindow have some other members (not only window handle) wich needs update?
