Most likely, yes. It's an operating system problem, not a device problem.
When you begin recording four channels, most systems give you the option of
recording either four mono files, or two 2-channel files. When it opens
those files (4 or 2), it doesn't do them all at the same time. So the
recording begins with a tiny time offset between the various files. I don'=

That's 4 milliseconds. Sound travels about 4 feet in 4 milliseconds. If
your microphones are spaced the 30 or 40 feet in Dan's recommendation, it's
a little bit as though you had moved one of the a few feet. No big deal.
But if the microphones are coincident, then it's as though they are suddenl=

not coincident. Big problem!
