st: Fw: Unable to combine graphs using -grc1leg-

[Gillian.Frost@hsl.gsi.gov.uk]

Hello,

I am trying to use -grc1leg- to combine two graphs produced using 
-marginsplot-, but I am getting odd behaviour.  Please not that -grc1leg- 
is a user written command available from 
http://www.stata.com/users/vwiggins

I produce the two plots using two separate -marginsplot- and save them. 
Firstly, I combined them using -graph combine-, which works fine.  I then 
try to use -grc1leg- but I get an error message (exact commands and error 
messages are below).  After I have unsuccessfully tried to use -grc1leg-, 
-graph combine- no longer works and I get a partial plot with an error 
message - the right plot is missing and the left plot has just the box.

Can anyone shed some light on what might be going on?

I am using Stata/SE 12.1 for Windows (32-bit), updated to 30 Jan 2013.  We 
are not yet able to install the 25Feb2013 update, but hope to have it 
soon.

Many thanks,

Gillian
