You need to be pretty careful about opening and closing HDF files in
IDL. For example, if you open a HDF file, and then your program crashes,
the most reliable way to make sure everything gets reset properly is to
exit and then restart IDL. You could probably use error trapping to get
around this, but exit/restart is quick and easy.

Cheers,
Liam.
