Verify BUG - jit.desktop can't export image max 7 x32 Windows x64

tada's icon

hi fellows

jit.desktop sends data to jit.matrix but cannot be exported (via exportImage) to a single png file.
How can this be possibe when jit.matrix loads correctly the data?

max 7.2.3 32 bit (I know that jit.desktop is not working for max x64 )
windows 8 64 bit

the first option exports in my pc a black image

ok I found the problem. The exportimage message needs Alpha plane=256 in order to work.
The patch corrected.
