hey thanks for this Jim eh.
I'd never have thought of looking there.
I did take a look through there, and then, out of interest, did a search
using windowsFind on, SendMessage
through all files, and only found one file which came up! and that was an
NVDIA file. That's kinda weird though, as I'm almost positive JSonar uses
that function in it's jss file somewhere. hmmm.
unless that's postMessage? have to check on this an get back to people.
