Since upgrading to LabVIEW 8.0 (including 8.0.1), I'm noticing what appears to be a bug with slider controls. If a program changes a slider control value (via a local variable or property node) in response to a slider value change event, two additional slider value change events are triggered. This behavior is as if I had set a pair of Value (Signaling) properties. Oddly enough, the two erroneous events are not generated if the user initiates the event by changing the "text ring" on a slider control having text labels turned on instead of manipulating the slider thumb.
Note that this problem is different from the slider control event issues in earlier versions of LabVIEW where moving a slider could generate an event for every intermediate value the slider passed through.
See the attached file for a demonstration of the issue. I have not found an acceptable work-around yet. Let me know if you know of one or if NI developers will be addressing this issue.
