multiplotER and Neuromag data

Dear all,
I tried recently to "multiplotER" some data coming from a Elekta Neuromag
system, and what I get is just a "grey" plot (see attachment), without any
scale and/or data, and no errors on the stdout. All the labels are fine, and
if I go in the interactive mode, I can zoom and see correct "singleplotERs"
... So, all the info seems to be there, just the "big" multiplotER is wrong.

I did some homework, and the thing doesn't seem to happen with (very!) older
versions of fieldtrip, i.e. I tried with a recent version (fieldtrip-20100209)
and a older one (fieldtrip-20091201), and the  multiplot is still grey,
whereas with and old (fieldtrip-20090318 !! that was somewhere in my HD ;-))
the multiplotER is displayed correctly.

Any hint? Am I doing any silly mistake?

Thanks in advance,

PS: I'm using Matlab (64bit) 2009b on Linux-64, if relevant ...
PPS: here is the code I'm using ... and yes, I tried also with the "ft_"
version of the commands

cfg                         = [];
cfg.dataset                 = 'raw.fif';
cfg.trialdef.eventtype      = 'STI101';
cfg.trialdef.eventvalue =  	32768;
cfg.trialdef.prestim        = 0.1;
cfg.trialdef.poststim       = 0.25;

cfg = definetrial(cfg);    = {'MEG'};
cfg.blc        = 'yes';
cfg.blcwindow  = [-0.1 0];
cfg.lpfilter   = 'yes';
cfg.lpfreq     = 35;
data_raw       = preprocessing(cfg);

cfg = [];
data_avg = timelockanalysis(cfg,data_raw)

cfg = [];
% cfg.showlabels = 'yes';
% cfg.fontsize = 6;
% cfg.interactive = 'yes';
cfg.ylim = [-3e-12 3e-12];
cfg.interactive = 'yes';
multiplotER(cfg, data_avg);

The aim of this list is to facilitate the discussion between users of the FieldTrip  toolbox, to share experiences and to discuss new ideas for MEG and EEG analysis. See also and
