[labnetwork] Savannah ALD GUI crash - empties the N2 cylinder

[Youry Borisenkov]

Hi Tony,
We are on LabView V8.0; and the Savannah ALD software is V18-24.vi
The situation I described, it indeed different.
As a matter of fact, I got a response from Veeco representative and I hope
he will be able to provide valuable input.

Thank you and have a great week!
Best regards,
Youry
