[xmonad] Windows Extending to Both Monitors in a Dual Monitor Setup

[Eyal Erez]

Hi,

I've been using xmonad for some time, and I've never seen this problem before.
I'm using it on my laptop, which I sometimes connect to a projector or
to a monitor
using a dock.  This has always worked fine.  However, a few days ago,
it suddenly
started stretching my windows across both monitors instead of keeping
them tiled on
one or the other.  It's as if xmonad thinks I actually have one really
wide monitor instead
of two.  I'm not sure where to start looking to fix this, since I
didn't really change
anything significant of late.

If anyone can point me in any useful direction, I would really appreciate it.

Thank you,
