Hi Nate & GodOfWar (and others),
I replaced the '*double_buffer' with plain 'double_buffer', but while
compiling it comes back with:
48:warning: passing arg 2 of 'movedata' makes integer from pointer without
a cast.
(This is why I initially used the '*double_buffer') Somewhere else is this
giving me a headache, but where? Must have ovelooked something.
