Writing Digital output problems when clicking START windows button

[raeletro]

I'm using a PCI 6025 on Win98 with NI-Daq 6.9.1. When run a VI that writes to one digital line output and then click on the windows START button, the output changes state. It writes 0 and 1 randomly. I tried even using the Intermediate level vis but it still happens. What should I do ?

Hi RA Eletro,

Please post a sample VI that exibits the behaviour you observed, we may be able to help.

Hello;

It's looking like there is something particular on your Labview VI that is causing that to happen. Could you post your VI so we could take a look at and figure if the problem is really there?
Regards.
