probe windows disappear on Block Diagram

[topside]

Hi all,

I came across an odd issue yesterday using the probes in Labview 2011. When I attach a probe to a wire and leave the probes inside the probe window they seem to work fine, however as soon as I launch the probes as separate windows, then click the title bar to move it to a convinient place they seem to disapear from the block diagram. Once this happens the probes no longer function and simply retain the values they had before they removed themselves.

I have attached a couple of images to show what I mean:

probe-window.jpg shows everything working as normal with the values in each probe acquired correctly.

separate-window.jpg shows what happens when I launch the probe windows and try and move them. They disappear from the BD and no longer function as probes.

Not a major issue I know but one I find very annoying as I like to move the windows to meaningful positions to clearly tell me which wire the values are coming from on the BD. I couldn't find anything similar on the forum so I don't know if I'm the only one with this problem, but it definitely did used to work!

Any ideas?

This seems weird. Did you check again with the same way and is it happening consistently? If yes try copying the code to a new vi and repeat the same. I don't have the answer for that but am also curious to know what is the reason behind this.

I initially noticed it happening in a different VI but it happens in any VI instance I open i.e. the one shown in the attachments. It is as though once I launch the probes from the main probe window they are no longer are part of Labview. I haven't installed anything new recently on my PC and I use probes in this manner all the time so I can't think why this problem is occurring.

I can't replicate the condition. Have you tried to run a repair on your LabVIEW installation?

By the way, there is a much simpler way (and more scalable) approach to accomplishing what you are trying to do:
