Help me. I sometimes get a error on line 122 or line 121 (the line that says gdk::draw_rectangle($this->w_imgedit->window,$this->gc,true,$x,$y,9,9);) but not always, only sometimes. Sometimes it stops after a while and generates a error message on that line, saying the object doesn't exist or is the wrong type. It only does it on that line, and only sometimes. Do you know how to fix this, please?
