In quiz, "Undo" and "Clear Kanji Pad" don't work when answer is shown

[GoogleCodeExporter]

I'm using Aedict 3.8 on Android 4.0.4. During the Kanji Draw Quiz, if I show 
the answer and then tap my menu button, the "Undo" and "Clear Kanji Pad" 
options don't seem to do anything. It would be cool if they would work while 
the answer is being displayed, so I could clear the pad and practice writing 
the kanji again while looking at the stroke order diagram.
