Processing全屏显示出错.

林定祥

用processing2.2.1,按Control+Shift+R,想实现全屏,结果有以下提示,请那位大侠指点下发生什么问题了?
java.lang.RuntimeException: java.lang.ClassNotFoundException: --full-screen
        at processing.core.PApplet.main(PApplet.java:6686)
Caused by: java.lang.ClassNotFoundException: --full-screen

PS:Control+Shift+R运行其他程序是好的,运行现在这段程序Contol+R也是好的(最大屏,不是全屏).
