I have recently encountered a problem with LabView 8.5 while I run the
software for a HighFinesse WS-7L wavelength meter (<a
href="http://www.highfinesse.com/ws7.php"
target="_blank">product
page</a>). In my VI, I am writing a value to one analog out channel as
well as two digital out lines. Every so often with the wavemeter software
running, the writing does not occur, although I get no error message and
the VI continues to run, seemingly waiting for the writing steps in the
sequence to complete. The only way to get the VI working again is to quit
and restart LabView. When I am not running the wavelength program, I don't
encounter this problem. Has anyone else experienced this problem, and is
there some workaround or explanation for it?
