When I use an non-existent PV via labCA in matlab, my matlab

hangs for a minute or two, then takes down matlab.

Hitting control-c during the timeout also crashes matlab.
I'm running matlab 7 under linux. I picked up what looked like the
most recent

labCA (2.0 alpha).
Can labCA be made to do anything other than hang and crash, like
print a

'Channel connect timed out' error?

For what it's worth, the matlab channel access interface
that we use at the SNS, some history of which is on
   http://ics-web1.sns.ornl.gov/mca.html
doesn't seem to have _that_ problem.
If you're interested, I can email you a snapshot of the current sources
from our CVS repository. I think the tgz on the web page is quite old.
I cannot, however, offer any more assistance with it.
