That's indeed a strange bug, and thanks to your detailed explanation I could easily reproduce it. The problem was that in the ELCode toolbar there is already a "SIZE" parameter, which gets submitted instead of your "size" attribute. Therefore whatever you submit as "size", gets replaced by zero (since the SIZE drop-down box usually sits at zero). So you can either go and change your "size" attribute into someting else like "Memory Size", or you upgrade to version 2244, where I fixed this problem.
