I had the same with LabVIEW in Windows. Then I repeated that with pure C
and, fortunately, Jeff was at SNS and saw the source of problem. That
was bug and there is Mantis by Jeff Hill.

It was fixed in 3.14.8 but I haven't tested yet.

Thanks, Andrei.

I think you're right about the support.
I use mca here at the SNS, and recently merged changes
that Steven Banks (Australian Synch.) emailed.
See http://ics-web1.sns.ornl.gov/~kasemir/mca .

But I don't think anybody is 100% familar with the sources
and has time to fix everything. Issues I know about:
- There are no unit tests for anything.
- I observed an occasional "No channel exists for this handle." error,
   but it's not reproducible.
- Occasionally, Matlab crashes on exit after having used MCA.

For me, it still works well enough to be of a lot of use.
