I'd like to thank all those who responded to my posting of yesterday. The
response indicated that there are others who are having similar memory problems.

The following came from Mariela Garcia of National Instruments:

>Dear Mr. Tenney,

>What you are describing is a unusual system problem. When LabVIEW or any
>other application quits, the system is in charge of disposing or freeing the
>memory.

>What version of LabVIEW you are running? What is the version of the system?
>Do you have any disk optimization application running in the background?

>The versions of LabVIEW compatible with the Quadras will be any LabVIEW
>2.2.1 or later.

>Maybe you can install Mac O/S 7.1 in your system. It could be possible that
>your current system is seeing the memory fragmented after LabVIEW quits,
>because of the system itself or because of a conflict with other
>applications.

>Give us a call if you need anything else.

>Sincerely,
>Mariela Garcia
>Application Eng.

Gary Johnson has also suggested that we could be having a problem with a CIN.
This could be a possible, we haven't attempted writing a CIN yet, but we have
software from Spectral Innovations and Metric System that has CIN's.

Our Quadra is running 7.0.1, but I discovered that the Tune-up had never been
installed. We have a data acquisition/DSP card from Spectral Innovations and a
library of vi's from them for signal processing. We also have the SurfaceView
3-D plotting vi's and use them quite alot. There is no disk optimization
package, but we do run Retrospect in the evenings to a DAT storage device.
