Sarah, Thank you.

I am working with my client to get the version information and maybe to
update to the latest versions. (He says that he has 2 versions. "Older
version, sent with previous data loggers is 5.08.11. The newer version
CD is labeled R.18. I'm going back this AM to recheck this as that
number was not a listed version on the website." ) When we more definite
info, I will e-mail you.

For others reading this: Do you know if leaked windows handles under
WinXP can cause lack of screen painting after several days running?
Other applications like NotePad and File Explorer can be started up and
seem to work just fine -- while the problem application is suffering.
Are windows handles limited in number for each application?

Thanks, JohnH
