I assumed that this meant you resume from standby with X server and emacs 
running and see this behaviour, but I'm having a little difficulty reconciling 
that with the log below, so can you clarify if I've understood correctly.

Well, in fact it seems that this isn't treated as a fatal error, but perhaps 
it should be...

Thanks.

Hmm... well, this is not as easy as it might be to interpret (I need to find 
my patch to add timestamps to the log and make it work properly...), but this 
looks like the multiwindow mode internal WM client isn't able to connect to 
the X server at all.

Normally you should get lines like:

winInitMultiWindowWM - DISPLAY=127.0.0.1:0.0
winMultiWindowXMsgProc - DISPLAY=127.0.0.1:0.0
winInitMultiWindowWM - XOpenDisplay () returned and successfully opened the 
display.
winMultiWindowXMsgProc - XOpenDisplay () returned and successfully opened the 
display.

So I'm a bit baffled as to how your windows are getting decorated at all...
