LabVIEW 2010 color pop up on graph legend sometimes disappears when mousing over it

[Thomas_robertson]

The attached picture shows what I'm talking about (when it is working properly).  This right click pop up menu on graph legends, and specifically the color pallet underneath that, occasionally disappears when the mouse hovers over More specifically, as soon as the mouse enters the color pop up window, it and the parent pop up right click menu both just disappear as if you had never right clicked on the graph legend.  

We've seen this on two different machines by two different users and it's just started happening in LabVIEW 2010 (admittedly we weren't running 2009 for long though, but we definitely did not see it in LV 8.6).  

One user saw this for about a week and then it went away (we do not yet understand the conditions which cause it to happen, or to go away), another user is now having the same problem.  On the same machine they are running a previous version of our software compiled in LV 8.6 without this problem.

Hi Thomas,

Do you have Nvidia nView display management software running on this machine? If so, Try disabling nView and that should solve the problem. Here is a KnowledgeBase article about it.

Neither of the machines is using that software.

One is Intel chipset, the other is using NVIDIA chipset, but isn't using that display manager.

Since it is an intermittent issue, I would try to pin down the conditions for when it happens. That will help find a potential fix for the problem. 

One thing to look at is if there are any other programs running when this happens. Another thing to look at is if the code changed at all between the one compiled in 8.6 and the current version.
