#1007 fix-be CAREFUL before merge

I checked the source and found the size of screen menu image is 60x60 px
and the caption is 16pt
It seems fine but I still don't know why it shows as image 81x81 and caption 22pt.
so I made some changes according to Tim Windsor's comment,
and asked some z30 users to test the broken-menu-app with fix, they told me it works fine now.

so,be careful when merging, since I don't have a z30 device and can't test this out seriously.

Thank you @tneil.
maybe @timwindsor can have this tested?
