Re: [dev] [PATCH] dmenu: Add commandline-options to determine Xinerama-screen

[Rob]

Hi,

Sorry to thread-dig here, but I've had trouble with dmenu recently and
traced it to this patch. The XCreateWindow call would fail because mw
would be zero. I'm unsure why, but this problem only happened when
Firefox or OpenOffice were focussed. Anyway, I've sorted it, the patch
caused dmenu to access past the end of the info array and a quick bounds
check fixes it.
Thanks, Rob.
