Button/Boolean mouse hover not working on 64 Bit LabVIEW

The other problem might be memory deallocation.

 

As this turns on and off for me during development, and apparently 50\50% during startup for others, this could be due to Windows moving LabVIEW memory. This in combination with 64 bit pointers...

 

That could be nonsense, I've lost track of the low level stuff when SSE was introduced.

I'm firmly with Zyga on this.  The behavior is extremely annoying and the issue has been out there for over a year without being resolved.  There are specific reasons that I'm using 64-bit LabVIEW, so I can't just switch to 32-bit.  When applications are delivered to customers and basic things like the mouse hover effects don't work properly, it strongly feeds into the notion that LabVIEW isn't a "real" solution for developing applications.  Even if the issue isn't a show stopper, it is detrimental to the reputation of LabVIEW and to all of us as developers.

No one has been able to reliably reproduce the issue; how can you fix what you don't understand?

 

A bug like this does make me frown, though.

NI did reply that they where able to reproduce. Not reliably, but still. At least it's a 'only in the wild' bug. That would make it much harder.

Hey there,

 

I totally agree. A GUI bug like this one shouldn't be that hard to fix (that's why I started this topic). As a workaround, I switched all my boolean controls to the "Silver" based ones. They don't have the hover states (False, False to True, True, True to False). This is definitely not a fix, but at least the users of my software won't get confused by the buttons being stuck on hover states.

 

Kind Regards,

Milad

My 'fix' would be to revert to my old solution.

 

I'm in luck that my mouse hover state is the same image as the true state. So I can actually monitor the mouse enter event, and switch the button to true. On a mouse leave event, I switch back to false.

 

But that's the old solution, and I did change it for a reason. I'd prefer LV to handle this... I'll wait until I get complaints for the users, it's just decoration in my application.

*Sigh* Mend to say: "At least it's NOT a 'only in the wild' bug."

Apparently, bugs like this ARE that hard to fix (that's why NI started NXG)

Hello everyone,

 

I know it's quite an old post but I am facing this bug right now.

I have been obliged to move from 32bit to 64bit for memory reasons.

 

I could not find any information or update on CAR #718053

 

I’m on LabVIEW 18 64bit with windows 10 Professional. As describe in this post, it happens quite often but unfortunately it appear to be random.

 

I was writing here to know if by any chance another workaround or fix have been implemented.

I've not found a way to:

+ reproduce this,

+ prevent it,

+ fix it...

 

It happens seemingly random, and when it happens it doesn't go away.

 

A workaround is to manually handle the hovering, by catching the mouse enter\mouse leave events, and switching the boolean value, or showing\hiding another control.

 

Probably not the news you where hoping for... It is what I had before, and I'll go back to this when my customer notice the bug and wants it fixed.
