[SOLVED]: Running COMSOL in batch mode without the meshing / solver window popup. Bug?

Hi All
I run COMSOL in batch mode remotely from the command line, and moreover run matlab scripts in COMSOL. What I want to do is run COMSOL from the command line with something like this:
$ comsol matlab -ml -nodesktop -ml -nosplash -mlr "myscript"
The problem is that COMSOL will try to pop-up a meshing status bar and a solution progress bar which errors my model with a null pointer exception since it doesn't know which display to send the window to.
I've tried looking up batch mode options, but those only seem to work when you're running .mph files -- for my problem, this is not an option.
Is there actually a way to do this?
Thanks,
Sumedh

After a bit of digging, I've found the answer, and for everyone's benefit (I hope) I'll demonstrate below.
Basically, you have to either add the following line to your matlab script:
>> flreport('off');
Alternatively, you can do this:
$ comsol matlab -ml -nodesktop -ml -nosplash -mlr "flreport('off'); myscript"
Both work just fine.
