apparently, you don't know a whole lot about ini files in general =\
not saying that all ini files are like this anymore, but... the restriction isn't a "cap" -- it's a restriction in most all ini files, simply because the way they are read.
this is very similar to the "64k cap" you would run in to while coding a QBasic program. why it's at 64k, i have no clue.
if you can write something that would make it go over 64k, i think we would all benifit from it
